Astronomical applications of a computed tomography imaging spectrometer with an adaptive optics telescope

先进的光电系统(AEOS)将被用来评估同时采集31个光谱波段的自适应光学补偿图像的仪器和技术。该仪器是一种计算机断层成像光谱仪(CTIS)，可最大限度地提高望远镜吞吐量，以实现三维图像堆叠的同时积分，其中堆叠图像的第三个维度是波长。在焦平面上使用光圈光圈来定义视场边缘的主光线。该系统应用了计算机生成的二维色散全息光栅，它产生0级直接像和一、二、三级像。科学应用包括调查共生星、原行星系统周围的大范围区域，以及识别微弱的伴星。***

Hege0088598AbstractThe Advanced Electro-Optical System (AEOS) will be used to evaluate an instrument and technique for simultaneously collecting adaptive optics compensated images in 31 spectral bands. This instrument is a computed tomography imaging spectrometer (CTIS) which maximizes telescope throughput to enable simultaneous integration of a 3 dimensional stack of images, where the third dimension of the stack is wavelength. An aperture stop is used at the focal plane to define the chief ray for the edge of the field of view. The system applies a computer generated, two-dimensionally dispersing holographic grating, which produces a 0-order direct image and 1st, 2nd, and 3rd order images. Scientific applications include investigations of extended regions around symbiotic stars, proto-planetary systems, and identification of faint companions. ***
