Abstract : Direct, real time digital data recording of thermal imagery is realized by the utilization of a computer that receives and stores bursts of high speed data from the digitized analog output of an infrared camera and simultaneously transfers a uniform flow of the data at a lower data rate to a digital tape recorder. The computer receives data only during camera active scan periods but transfers data to the recorder continuously. By making the computer output data rate substantially equal to the average input data rate real time recording is achieved. Full utilization of the data handling capacities of both the computer and the lower speed recorder is accomplished by digitizing the camera output signals in 8 bit words, combining pairs of 8 bit words for 16 bit word processing in the computer and reconverting the computer output data to 8 bit words for recording by the digital tape recorder.
