  • Spectrally Adjusted Surface Reflectance and its Dependence with NDVI for pAssive Optical Sensors

    Cross-calibration between sensors is necessary to bring measurements to a common radiometric scale; it allows a more complete monitoring of land surface processes and enhances data continuity and harmonization. However, differences in the Relative Spectral Response (RSR) of sensors generate uncertainties in the process [1]. For this reason, compensating for these differences is of great importance and can be achieved by using a spectral band adjustment factor (SBAF), which establishes a relationship between two spectrally adjusted bands. Nonetheless, this relationship has been shown to depend greatly on the surface type [2] and therefore needs to be corrected. In this work, we compute the SBAF between the historical Landsat and Sentinel 2 sensors by using the RSRs of different passive optical sensors in the Green, Red and NIR bands and the surface reflectance spectral libraries (ASTER, AVIRIS, IGCP) with a wide variety of classes. We produce a quadratic fit of the SBAF vs the surface's NDVI (ρnir- ρred)/(ρnir+ ρred) and propose an exponential correction equation dependent on the NDVI value for both bands. A comparison between Landsat 8 and Sentinel 2 images using the HLS product shows that this method improves the red band and NDVI accuracy by 46.4% and 63.9% respectively when the difference between the Relative Spectral Responses (RSR) is significant, but is inaccurate for the green band, where the atmospheric correction is likely to introduce same order errors.

  • Optimal design of nanoengineered implantable optical sensors using a genetic algorithm

    A genetic algorithm as a design tool for optimized optical glucose sensors is presented. These proposed sensors are fabricated by assembling ultrathin polyelectrolyte films on the surface of calcium alginate microspheres containing glucose oxidase and an oxygen-quenched ruthenium fluorophore. The sensors are rendered ratiometric by inclusion of a complementary reference fluorophore via polyelectrolyte-dye conjugates. The genetic algorithm, in conjunction with a computational model of the chemical sensor, selects the optimal values for diffusivities of glucose and oxygen in the polyelectrolyte films, the enzyme concentration, microsphere radius, and film thickness that give the optimum sensor response. The values given by the genetic algorithm will be used to design future sensor prototypes.

  • Characterization of Optical Sensors for Real-Time Measurement of Motorcycle Tilt Angles

    An effective optical sensor for real-time measurement of the tilt angle in high-speed motorcycles was developed and tested. The basic idea and target of this work is to create a compact, reliable and also low-cost optical triangulators capable of accurate in-field measurements, in the harsh environment of sport motorcycles. Calculations of the required system sensitivity and allowable accuracy are described for this kind of optical sensor. The first prototypes, based on LED emitters, demonstrate the viability of such optical solution but they suffer from significant performance degradation due to solar interference, moved at high Fourier frequency by the combined effect asphalt roughness and motorbike speed. A second-generation instrumentation is under study, relying on laser emitters. Such novel triangulators promise good and reliable performance for the proposed application, keeping low costs and encumbrance and overcoming the problem of solar interference.

  • Optical sensors

    Optical sensor development has been pursued over past 25 years, which has also seen development of novel chemistries, materials, sensor designs and optical instrumentation. In addition, novel signal and data processing techniques have been adopted in the sensor development. New techniques and materials in chemical and biological sensing have set further stages of advanced research. One of the most recent technological advances in this area has been the development of optical nanosensors, which are sensors with dimensions on the nanometer scale. Nanosensors of various types (e.g. optical, electrochemical) have been published in the literature over the past decade. Optical nanosensors, like the larger and macro scale sensors, can be either chemical or biological, depending on the type of probe used. Both types of sensors have been studied to provide a reliable method of monitoring various chemicals in microscopic environments and have been used to detect molecules within single cells. The field of nanosensing is relatively new and reports in the literature presenting any problems associated with such a scale of analysis are sparse. This paper will briefly review some of the current developments in the field of optical nanosensors.

  • Optical sensors based on electrochromic conducting polymers

    Conducting polymers have been widely applied in various sensing platforms. The application of conducting polymers in optical sensing systems is shortly overviewed and discussed in this paper. Some studies on pH, halide anions, heavy metal ions and gas sensors are presented along with their sensing characteristics and possible fields of application. Interactions that lead to a change in optical properties of conducting polymers and production of analytical signal for different analytes are explained briefly.

  • Dual-band UV/IR optical sensors for fire and flame detection and target recognition

    Several military and industrial applications require simultaneous or at least spatially synchronized detection of optical emissions in different spectral regions. The ability to grow III nitrides on Si wafers is considered to be key to the development of multi-color detectors ranging from the UV to IR wavelengths. GaN/InGaN p-n heterostructures grown on Si wafers indicated sensitivity in a wide spectral range from near UV to near IR. Employment of Schottky barrier photodiode structures based on AlGaN alloys allows extension of the spectral sensitivity further into the UV range beneficial for solar- blind sensing. An alternative way to combine sensitivities in separated IR (provided by silicon) and UV (featured by III nitrides) bands by employment of commercially available silicon-on sapphire (SOS) wafers is discussed.

  • HPM Testing and Transmission Measurements on Optical Sensors

    This paper is a summary of a study made with regards to optical sensors in an high power microwave (HPM) environment. This study included coupling measurements through different optics, high power testing of built-in shielded optical sensors and susceptibility testing of unshielded optical sensors with electromagnetic radiation for microwave frequencies. The purpose of this study is to determine if it is possible to make coupling measurements and susceptibility testing on the unshielded sensor, and from these two measurements estimate the HPM susceptibility of a shielded sensor, where the optical aperture is the only transmission path for radiated microwaves. The study also addresses conclusions about the coupling path and the HPM threat on optical sensors.

  • Novel FTO/SRO/silicon optical sensors: characterization and applications

    In this paper, we describe the electrical and optoelectronic properties of new metal-insulator-silicon optical sensors, in which the silicon rich oxide layer is used as leaky insulator. Due to a leakage current through the insulator layer, two possible operating modes have been found for sensors. At the first mode and at certain voltage bias, the sensors are likewise photodetectors with an abrupt p-n junction. The second operating mode when the sensors investigated have the properties of a "usual" MOS capacitor takes place at a lowered bias. We show the possibility of combining these operating modes by applying to the structure a mixed DC and pulse voltage bias. With this, transient processes taking place can be used for the design of new optical sensors with internal signal gain.

  • Comparative Design and Synthesis of IR and Optical Sensors for Fluid Flowrate Using FPGA

    Accurate liquid flow rate measurements reduce the ambiguity in applied quantity of dosage, determine the leakage rates and increase system efficiency. The aim of this paper is to focus on the advantages of IR & optical sensors used with the FPGA technology. The two flowrate sensors based on IR and optical technology are designed and compared in the work on the basis of power consumption, delays taken in the processing, and required hardware. This paper also focuses on the FPGA platforms, their features and advantages over microcontroller and DSPs. The microstructured flowrate sensors are more suitable in chemical industries, commercial application where exact additive mixings, dosages play critical role.
