NASA Remote Imaging System Acquisition: Space Environment Multispectral Imager

Abstract

This project seeks to design and build a camera suited for the space environment. It is an imaging camera that operates between 350 nm and 1050 nm wavelengths, with a Matlab user interface. The camera uses a (-mount standard interface to a (MOS detector, and has a fixed focal plane when operational. Focus adjustment for objects from infinity up to a distance of 2 meters is made possible through the implementation of a liquid lens. Developed by Varioptic, the liquid lens changes its optical power relative to the voltage potential between its two faces. This novel technology will allow for wireless, remote camera operation without fear of mechanical parts failure. Lens system design and analysis was achieved through Code V, lens barrel design was done through Solidworks. The camera is insulated to withstand a temperature range of -20 to 50 degrees C, and the optical components are protected in an air-tight seal by two plane windows at either end of the barrel. Excepting one element, the glass lenses and liquid lens are spaced by aluminum spacer rings and secured by an aluminum retaining ring. One lens is secured by an optical UV curing adhesive. The barrel is aluminum 6061, anodized black.
