Abstract
In order to give consideration to both resolution and swath of airborne remote sensing instrument, pan-sharpening method was used to get high resolution pan-sharpened image. This research provides a description of the optomechanical system design and assembly of airborne imager, VCDi-660 (Vegetation and Change Detection imager). Opto-mechanical components of VCDi-660 consist of six optical lenses, focal plane adjustment, bore sight alignment adjustment, filter-exchanging mechanical device and circuit protected housing. An improved adjustment device for bore sight alignment of the multiple-band camera in this Taiwanese airborne imaging sensor, VCDi-660, has been presented. Target of this mechanical device is to provide a translational and rotational movement in the focal plane of VCDi-660. Sensor can be aligned into the best focal position, thus the central point deviations for individual camera module can be less than 3 pixels in both axes in image after alignment.
