Abstract
This paper describes a recently developed transmissometer that can be used to measure atmospheric extinction in different spectral bands in the visible and infrared spectral regions over field ranges up to 8,000 meters. In addition to functioning as a transmissometer the instrument is capable of measuring remotely the apparent radiance emitted or reflected from objects that are located within the starring field of view. In the normal system configuration the transmissometer/radiometer consists of silicon, InSb, and HgCdTe receivers and two multi-color searchlight sources that together allow transmission or radiance measurements in the spectral region of 0.4 to 14 micrometers. Included in the paper is a description of the equipment, the calibration procedure, a typical field measurement, and a discussion of typical transmission measurement results obtained from a variety of recent field deployments.
