1. Hyperspectral Image Projector Applications
Published: 2/15/2012
Authors: Joseph Paul Rice, Steven W Brown, David W Allen, Howard W Yoon, Maritoni Abatayo Litorja, Jeeseong Hwang
Abstract: For the past several years NIST has been developing, along with several collaborators, a Hyperspectral Image Projector (HIP). This scene projector produces high-resolution programmable spectra and projects them into dynamic two-dimensional images ...

3. Illumination with enhanced contrast as a visualization tool for clinical diagnostics and surgery
Published: 2/26/2009
Authors: Maritoni Abatayo Litorja, Steven W Brown, Yoshihiro Ohno, Chungsan (Mike) Lin
Abstract: The requirements for diagnostic and surgical lighting have remained largely unchanged over the past several years illumination level, glare, shadow and tissue heating reduction are the dominant factors in choosing a lighting system. Since human visu ...
