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

Hege0088598摘要先进的光电系统（AEOS）将被用来评估一种仪器和技术，同时收集自适应光学补偿图像在31个光谱波段。 该仪器是计算机断层扫描成像光谱仪（CTIS），它最大限度地提高望远镜的吞吐量，使图像的三维堆栈的同时集成，其中堆栈的第三个维度是波长。 在焦平面处使用孔径光阑来定义视场边缘的主光线。该系统采用计算机生成的二维色散全息光栅，产生0阶直接图像和1阶、2阶和3阶图像。 科学应用包括调查共生恒星周围的扩展区域，原行星系统，以及识别微弱的同伴。***

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. ***
