20 September 1976 Viking Lander Camera: Performance Characteristics And Data Reduction Techniques

A facsimile camera was selected over several other types of imaging systems that had been proposed for the Viking lander mission to Mars primarily because it could best meet stringent power and weight constraints. The reason is that the optical-mechanical scanning mechanism of this device provides both the image raster and the field of view. In addition, the Viking lander cameras feature electronic focus selection for high-resolution (0.04 instantaneous field of view) monospectral imaging, six survey channels between 0.4 to 1.0μm for lower resolution (0.12°) multispectral imaging, and a (0.12°) survey imaging mode for rapidly viewing the scene (for example, 60° x 180° in 5.5 minutes). Absolute radiometric accuracies of about 10 percent can be attained with the aid of an internal light source and external reference test charts. The cameras are the most versatile imaging systems ever developed for a planetary mission. However, their performance is not without peculiarities that require meticulous care in reducing spatial and spectral data.
