Abstract

The Quad-Emissive Display (QED) is a device that is designed to provide suitable emissive energy in four spectral bands to permit the simultaneous evaluation of sensors with different spectral sensitivities. A changeable target pattern, such as a Landolt C, a tumbling "E", a triangle or a bar pattern, is fabricated as a stencil (cutout) that is viewed against a second, black surface located several centimeters behind the stencil and thermally isolated from the stencil target. The sensor spectral bands of interest are visible (0.4 to 0.7 microns), near infrared (0.7 to 1.0 microns), short wave infrared (1.0 to 3.0 microns) and the long wave infrared (8.0 to 14.0 microns). This paper presents the details of the structure of the QED and preliminary results on the types of sensor/display resolution measurements and psychophysical studies that can be accomplished using the QED.
