33processing module by a scan converter. To optimize the sensor's performance, <strong>array</strong> biasand clock levels are individually programmed. The specific timing requirement and thesize <strong>of</strong> the <strong>array</strong> can be adjusted by programming the timing generator and input buffers.Focal Plane Array AmpiirlersFigure 3.1 UFPA interface board block diagram.The majority <strong>of</strong> the sensor functions are performed by the video processingmodule. The tasks include image processing functions <strong>of</strong> "equalization", or nonuniformitycorrection, and scaling the dynamic range <strong>of</strong> the detector to the temperaturespan <strong>of</strong> interest. The user interface for measurement modes, temperature spans andranges, setup menus, colorization, zoom and cursor control is provided by the videoprocessing board also. Mass storage functions on a PCMCIA card as well as a commonfile format are available for storing and retrieving digitized images into the sensor. Forcommunications protocol, a standard remote control interface to the sensor is maintained.
