Abstract:
In the past decade, there has been an explosion in the exploitation of spectral, polarimetric, and wavefront diversity techniques applied to a number of scientific imaging and non-imaging problems. Utility of these methods has been demonstrated and in many cases has resulted in the development of deployable systems. Through high performance algorithmic processing, end-users are provided with automated information extraction and enhanced capabilities for the tasks of discrimination, classification and identification. These techniques are successfully exploited today in the studies of earth resources, biological interactions, astronomy, manufacturing process control and military intelligence gathering among others. In this paper, I describe a system that has been developed at the Advance Electro-Optical System (AEOS) which achieves high spatial resolution, high spectral resolution, and high sensitivity simultaneously, permitting configurability of spatial, spectral and sensitivity parameters for timeline and feature extraction optimization.
The AEOS Spectral Imaging System (ASIS) is a multi-spectral compensated imaging capability integrated with the 3.6m AEOS telescope located at the Maui Space Surveillance Complex (MSSC). The optical implementation, sensors and processor architecture that have been developed during the past two years are described in this paper. The versatile implementation permits high sensitivity narrow-band, diffraction limited, compensated Adaptive-Optics (AO) imaging. ASIS has been designed to achieve highly synchronize multi-channel image data acquisition in the visible (VIS), near infrared (NIR) and short wave infrared (SWIR). Field de-rotation and Atmospheric Dispersion Compensation (ADC) permit high performance imaging and multi-frame processing from zenith down to near horizon. Additionally, the ASIS optical layout incorporates access ports for accommodation of auxiliary instruments and can support AO compensated data collections for other modalities. The ASIS system has been used to validate Model Based Spectral Image Deconvolution (MBSID) techniques and is also host to an imaging Stokes polarimeter.
