Real-Time Vis-SWIR Multispectral Sensor for Day/Night Operations

The 3D camera technology is a recent imaging technology for multispectral imaging, developed recently at Surface Optics Corporation. This camera system is a compact solid-state staring multispectral imager that captures the information required to generate complete multispectral cubes with each focal plane exposure. The number of bands depends on the number of spectral filters used in a mosaic filter array. The program proposed here will develop and analyze an optimized design for a 3D camera operating in the SWIR waveband. This will produce a video rate camera for making real-time SWIR multispectral measurements. The system will use high density InGaAs focal plane arrays that are now in development. Two fore-optics will be designed for the system for wide and narrow fields of view. The system will include an integrated real-time processor for analyzing and displaying results in real time. The proposed program will produce a preliminary design layout and a detailed system performance analysis.
