“…However, LiNbO 3 single crystals are an attractive piezoelectric and ferroelectric material with excellent piezoelectric, ferroelectric, thermoelectric, nonlinear optical, electro-optical, and acousto-optical properties, and are widely used in modulators, detectors, sensors, integrated optics, nonlinear optics, information storage, and other devices. [12][13][14][15][16] LiNbO 3 single crystals are widely used in optics and are called "optical silicon" owing to their unique electro-optical, acoustic-optical, thermoelectrical, and nonlinear optical properties. 17 Meanwhile, LiNbO 3 is widely used in the preparation of acoustic surface wave and bulk acoustic wave devices because of its high-quality factors and large electromechanical coupling coefficient.…”

“…The photoelastic modulator (PEM) is a resonant polarization modulator operating on the basis of the photoelastic effect [1], which has the advantages of no mechanical vibration, a wide range of applicable wave bands (from the UV to the IR), and a high modulation frequency (tens to hundreds of kHz) [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The PEM-based Fourier transform spectrometer (PEM-FTS) is capable of providing greater than 10 5 interferograms/ spectra scanned per second [10], as opposed to a few thousand scans per second available spectral resolutions useful in the infrared is difficult.…”

The currently allowable photoelastic modulator based Fourier transform spectrometer (PEM-FTS) retardation-amplitude is low, and spectral resolution is relatively poor. This paper presents a method for high retardation-amplitude whose PEM is based on microtrapezoidal photoelastic crystals and Herriott-PEM. The retardation-amplitude of the improved PEM is about 19 times larger than an ordinary PEM. The ultra-high speed infrared spectroscopy remote measurement prototype is designed based on high retardation-amplitude PEM. The best spectral resolution of the prototype is 4 cm −1 , and the zero-crossing single sided interferogram scanning time is less than 5 µs.

In order to realize the continuous and stable, high speed, high precise and high sensitive measurement of optical rotation, and considering the application advantages of photo-elastic polarization modulation technology with high modulation frequency, high modulation purity, high modulation accuracy and good modulation stability, a new scheme about the measurement of optical rotation based on photo-elastic modulation is presented. Probe laser orderly passes through a polarizer, the rotation sample to be measured, a photo-elastic modulator, and a analyzer, and finally reaches the detector, this system uses less optical devices than any others previously reported, so it considerably reduces the measurement error that may be introduced by the optical devices. In the detecting of light path, the polarization axes of the polarizer and analyzer are respectively adjusted with respect to the photo-elastic modulator's fast axis directions 0° and 45°, the optical arrangements make the rotation angle to be measured appear in the alternating current signal, and the photo-elastic modulator's residual birefringence only appears in the odd harmonics. Consequently, the second harmonic signal of photo-elastic modulation is selected as the object to study, which effectively avoids the influence of residual birefringence of the photo-elastic modulator on optical rotation measurement, and efficiently improves the accuracy of optical rotation measurement. What is more, the detector output signal is separated into two parts, the direct current and alternating current signal. The alternating current signal is amplified, then outputs by a lock-in amplifier, which enhances the measurement sensitivity further. A ingenious verification test experiment is done, firstly, the probe laser is modulated into circularly polarized light, and then precisely rotates the polarizer to replace the optical rotation sample. The results show that the new scheme is feasible, this experiment gives the proportion coefficient of the measurement system, the sensitivity of optical rotation measurement increasing up to 3.15× 10-7 rad, and the measurement precision exceeding 0.3%. Therefore, in this scheme achieved is a high sensitive and precise measurement of optical rotation, and it is expected to be applied to the high sensitive and precise rotation measurement. The verification test experiment designed by us can also provide a outstanding calibration reference for high sensitive rotation measurement system.
