Abstract

The portable hyperspectral imager for low light spectroscopy (PHILLS) is a modular system incorporating panchromatic and spectroscopic imagers. PHILLS was designed to be a low cost, versatile hyperspectral imager using primarily commercial off-the-shelf parts that could be used as a ground based or airborne imager. The goals fo the PHILLS program are to allow collection of high quality broadband hyperspectral data, to develop methodology for near real time spectral unmixing, to make deployment of hyperspectral imagers feasible in airborne or spaceborne scenarios. Presently PHILLS combines high resolution color video cameras with intensified UV, visible, and NIR spectroscopic modules with wavelength resolution of 0.5-2 nm over the 0.2-1.1 micrometers band. The system offers analog and digital data recording capability with GPS annotation. The instrument has been successfully deployed on NRL's P-3 aircraft in missions from the North Pole to the Florida Keys. The PHILLS system is controlled by a personal computer and is integrated with an adaptive hyperspectral data analysis system that provides very fast end member determination and subpixel spectral unmixing using an orthogonal projection based method known as the filter vector algorithm.
