Abstract

An existing Barnes Engineering,Inc, slow scanning infrared spectral imaging system has been modified to accent an ultraviolet detector, thereby allowing for a two channel ultra-violet or infrared imagery acquisition system. The infrared optical channel has been al-tered to accept a beam splitter for redirecting ultraviolet scenery and transmitting infrared scenery. The ultraviolet optical channel further incorporates a relay lens, optical filters, and a photomultiplier tube detector. The imagery system controller has been changed to allow for interfacing to several data acquisition systems for increased mission flexibility. In existing data acquisition control system program has been modified to acquire and record data on computer compatible digital tape. Digital image data and synchronizing signals were extended from the original Barnes interface and made available for use by an external digital video real-time display. Existing data editing programs were rewritten to accommodate imagery data, and data reduction programs were written for gray level data reduction. Preliminary ultraviolet and infrared measurements have been conducted with some apparent optical performance and throughput degradations in the ultraviolet channel. References to ultraviolet negative/positive contrasts, atmospheric effects, and system optical performance were analyzed. Video and computer reduced gray scale plots have been acquired, and photographs of video gray scale scenery are presented.
