A computerized camera design and optimization technique is described. The model analyzes the performance using MTF techniques and determines the volumes and altitude range. One each of the camera design parameters are arbitrarily selected. Through an iterative procedure the focal length is computed, which provides the required ground resolution. The minimum operating altitude and camera size are computed. The process is repeated for six camera types, four film types, four film widths, seven F numbers and all combinations of supporting subsystems, which include four types of IMC, four focus control methods, five vibration isolator types, and two thermal control methods. The 107,000 combinations are then sorted into an increasing size order. The computer program may be interrogated for detailed dimensions. These dimensions are suitable for preliminary camera layout. Optimum selection of parameters such as film type, film format, and F number are clearly seen through sensitivity analyses. Sample results are presented showing benefits achievable through optimized miniaturization of an existing camera system.
