Infrared Image Acquisition and Analysis Method for Quantifying Optical Responses to Chemical Agent Vapor Exposure; Conference paper

摘要

A method was developed employing an infrared (IR) light source, IR capable video camera, digital processor and image acquisition/analysis software for quantifying pupil constriction resulting from nerve agent vapor exposure. Image acquisition and analysis routines were developed to capture images and automate pupil area measurements or manually analyze images based upon operator- selected parameters. The latter option is useful in cases where the pupil image is partially obstructed or pupil shape is other than circular. The method described here allows for remote/non-invasive assessment of the level as well as the time course of onset and duration of pupil constriction.
