Abstract

Low-cost CCD-based cameras offer several cost and performance advantages for remote sensing applications. The optomechanical design of such cameras is inherently simple because zoom, gain and yaw corrections can be performed electronically, thereby, requiring no moving parts or mechanisms. This paper presents the optomechanical design and the results of structural and thermal analyses for a low-cost camera consisting of only three major parts: lens, electronics and camera housing. This camera uses a wide field of view lens with a fast f-number to acquire high- resolution images under various day and night time illumination scenarios. Passive athermal design of the lens maintains a high value of the MTF over a temperature range of 110°C. Selection of the materials and adhesives used in this camera is dictated by a lifetime requirement of over 30 years under adverse environmental conditions. Structural and thermal modeling results confirm the survivability and performance of this camera under various shock, vibration and thermal loads.
