2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018
Development of ultrafast mid-infrared (MIR) pulse lasers has been in rapid progress over the past decade. Since a number of molecular vibrations have resonance in the MIR region, the ultrafast MIR pulse lasers are very useful for advanced molecular spectroscopies, such as frequency comb spectroscopy for the molecular fingerprint region, pump-probe spectroscopy to trace ultrafast structural dynamics, and control of ...

Development of ultrafast mid-infrared (MIR) pulse lasers has been in rapid progress over the past decade. Since a number of molecular vibrations have resonance in the MIR region, the ultrafast MIR pulse lasers are very useful for advanced molecular spectroscopies, such as frequency comb spectroscopy for the molecular fingerprint region, pump-probe spectroscopy to trace ultrafast structural dynamics, and control of photodissociation by selective excitation of vibrational states. The development of such a light source is also attracting more attention in the high field laser physics. The cutoff extension of high harmonic generation (HHG) driven by a long wavelength few- cycle pulse has been carried out, and generation of shorter attosecond pulses is predicted. Since it is a process within the single optical cycle of the driver electric field, it is very important to have a few-, single-, or sub- cycle pulse with a precisely controlled field oscillation, namely the phase control of the laser field within at least a few tenth of the oscillation period. In such an experiment, field-revolved detection of the ultrashort MIR pulses is essential since the cutoff of high harmonic generation is sensitive to the field strength of the driver laser pulse.
The reflection property of targets is the fundamental signal for applications of optical remote sensing of the earth's surface. In this paper, we measured the photometric and polarimetric characteristics of 15 leaves with different properties from one plant species (i.e., Pachira aquatica) using a laboratory goniospectrometer system and used the bidirectional reflectance factor (BRF) and the bidirectional polarized reflectance factor (BPRF) to describe the reflection of these leaf samples. The results illustrated that the BRF can be replaced by the I parameter reflectance factor (IpRF) when the extinction of the polarizer is considered. Subsequently, the BRF model was fit to the IpRF measurements at selected wavelengths, and the inverted refractive index was used in a BPRF model, which has been proposed to simulate the polarization of surfaces. We found that the modeled photometric results of all the leaves matched well with our measurement results over all the measurement directions, while the modeled polarimetric results of the leaves gave a good agreement with the measurements at the forward scattering directions. Moreover, the degree of linear polarization (Dolp) of the leaf, which is derived from the ratio between BPRF and IpRF, can also be effectively computed by the combination of BPRF and BRF models in the forward scattering directions. These findings suggested that more attention should be dedicated to the combination of BRF and BPRF of leaves in the future because we can completely describe the essential optical properties of the light reflected by leaves via the polarimetric measurement. This paper indicates that the polarimetric measurement is a beneficial method for optical remote sensing applications and helps us deepen the understanding of the optical properties of leaves.
A measurement system was developed to measure the electron beam spectrum of the Beijing free-electron laser based on the optical transition radiation (OTR). This paper describes the system, which consists of a 32-channel high resolution of 0.02% OTR detector, especially the spectrometer. The OTR angular-distribution pattern at the focal plane has two apexes, but the two apexes are smoothed out due to the electron beam energy distribution. The energy spectrum can be measured if the magnet energy resolution is higher than 0.7% to distinguish the electron beam energy distribution.

AC loss measuring methods of high-temperature superconducting (HTS) tapes and unit, generally consisting of electronic and magnetic as well as calorimetric techniques, have been mature and made great contributions to AC characteristics of HTS materials, research and development of HTS applications. This paper briefly introduces and summarizes the principles of AC loss measurement techniques, focusing especially on electric and calorimetric method for measuring AC losses of HTS tapes. A novel developed calorimetric method for measuring AC loss based on optical Fiber Bragg Grating (FBG) was introduced in detail. After comparing the sensitivities of various measuring methods, AC loss measuring methods available for HTS tapes and units are suggested.
A hydrophone scanning method is gold standard for the ultrasound filed measurement. However, the hydrophone scanning is time consuming especially for the three-dimensional measurement. On the other hand, two-dimensional data can be acquired simultaneously by an optical measurement method using a camera. In this study, the optical phase contrast method was used to measure a three- dimensional pressure filed generated by a focused transducer.
