摘要: A lamp, a film guide, and photosensitive detector are combined into an optical system contained in portable device that generates electrical signals representing images recorded on motion picture film. The guide has surface proximate to the with aperture therein through which light from lamp passes image detector. digital processor, is electrically connected processes electronic signal output by To provide compactness, folded path comprising three segments each separately mounted different surface. first segment includes second third An positioned so as receive enables adjusting when moved location where temperature other environmental conditions change. This configuration also finds use located environment whose remains consistently hot.
