高光谱分辨率傅里叶变换成像光谱学已经在洛克希德马丁先进技术中心得到了验证。利用迈克尔逊干涉仪和两级端镜控制系统搭建了实验台。零差激光测量用于感测干涉仪中的相对倾斜、倾斜和活塞，并且3自由度快速转向镜与线性致动器平台结合提供了超过20毫米活塞范围的亚纳米致动控制。活塞的范围内的信号是允许在可见光/近红外（VNIR）波段的光谱分辨率在纳米级的重建图像中的每个像素。
High spectral resolution Fourier transform imaging spectroscopy has been demonstrated at the Lockheed Martin Advanced Technology Center. A testbed was built using a Michelson interferometer with a two-stage end-mirror control system. Homodyne laser metrology was used to sense relative tip, tilt and piston in the interferometer, and a 3-degree of freedom fast steering mirror in conjunction with a linear actuator stage provided sub-nanometer actuation control over 20 millimeters of piston range. The range of piston over which signal was present allowed for spectral resolution at the nanometer level in the visible / near infrared (VNIR) band for every pixel in the reconstructed image.
