| 摘 要： | 对大孔径静态干涉成像光谱技术方案与以色列学者提出的两维景物光谱同时测量方法进行了分析和比较,讨论了这2种干涉成像光谱技术方案中干涉仪与成像光学系统两方面的差异,通过计算机模拟,给出了两维景物光谱同时测量方法的光程差非线性变化。受两维景物光谱同时测量方法的启发,提出基于横向剪切干涉仪的时间调制型干涉成像光谱技术方案,研究了匀速转动横向剪切干涉仪时,各不同视场像元处光程差的变化规律。

| Abstract: | The comparison between large aperture static imaging spectrometry(LASIS) designed by author and method for simultaneously measuring the spectral intensity as a function of wavelength of all the pixels of a two dimensional scene(MSMSI)designed by Israeli researchers is given.The difference of the intedemmeters and imaging systems in LASIS and MSMSI is discussed.The nonlinear curve of optical path difference of MSMSI is simulated.Inspired by the operation of MSMSI,the time modulated Fourier transform imaging spectrometry based on lateral shearing interferometer was presented.The optical path differences of different field of view were given under the condition of regularly rotating the lateral shearing intederometer. |
