23. Evaluation of a Portable Hyperspectral Imager for Medical Imaging Applications
Published: Date unknown
Authors: David W Allen, Maritoni Abatayo Litorja, Steven W Brown, Joseph Paul Rice, Yuqin Zong
Abstract: Portable hyperspectral imagers are becoming commonly available as a commercial product. A liquid crystal tunable filter based CCD imager was evaluated and characterized for spectral stray light using a tunable laser facility. The hyperspectral imag ...
