Abstract

Previous studies showed that two- and three-waveband color-mixing methods perform the optical equivalent of two- and three-wavelength band ratio calculations that are typically implemented using multispectral imaging to enhance target classification and detection. This paper presents a prototype two-waveband color-mixing binocular device for enhancing visual target detection and classification, as tested using Ishihara test cards. Target identification for the test cards in this study was improved by using two-waveband color-mixing binoculars fitted with filters centered at wavelength pairs selected according to the criterion of uniform background. The test-card imaging results demonstrate that color-mixing binoculars can be used to greatly enhance target identification and detection.
