Abstract

Images of a number of natural subjects have for some time been made using wavelengths longer than those to which film is sensitive. This has been done by use of instruments employing mechanical scanning and cooled semiconductor detectors. Some of this imagery is now becoming available for general use. In this paper, we describe some of the physical effects causing observable changes in the imagery, comment upon some of those factors observed in a selected set of images of both natural and man-made features recorded by the Bendix thermal mapper, and suggest some uses and potential uses for such data for some scientific and general purposes.
