Study of the Stark Shift of New Type Rubidium Atomic Optical Filter

新型铷原子滤光器斯塔克频移研究

In the detecting system of laser illumination and laser guide star ( LGS), the application of optical filter is an important approach to reduce background noise and improve signal-to-noise ratio ( SNR).

在激光照明和激光导星的探测系统中，运用滤光器（片）是抑制背景噪声、提高信噪比的重要途径之一。

This paper reports the theoretical study on the transmission efficiency, bandwidth and frequency shift of anomalous dispersion atomic optical filter with off axis incident beam.

本文首次对反常色散原子滤光器在斜入射（0～π/2）条件下的透过率、带宽和频移等特性进行了理论研究；

This paper discusses the method of coding the three_basic_colour image of the colour transparent film with a Ronchi grating and optical filter, recording it on a white_black film, and making a colour hologram with monochromatic laser.

通过使用Ronchi光栅和滤波片，把一张彩色透明片的红、绿、蓝信息编码记录在一张黑白胶片上并用单色激光制作彩色全息图。

The results indicate that, under the thermal noise approximation, the measurement accuracy of Brillouin frequency shift is dependent on thermal noise, the derivative of the transmission function of the edge optical filter and the power of Brillouin scattering optical signal.

结果表明，在热噪声近似下，布里渊频移测量精度与热噪声、边缘光滤波器透射函数的导数及布里渊散射光信号功率有关。
