Abstract:
An optical device with optional resolutions for converting an initial image into electronic signals by a specific resolution, comprising:a housing;a plurality of focusing units with various magnifying powers and various optical path lengths mounted immobily in said housing for variously proportionally receiving said initial image and generating a focused image;a photoelectric conversion unit mounted immobily in said housing for converting said focused image into said electronic signals;a light-reflecting unit mounted immobily in said housing and located between said photoelectric conversion unit and said plurality of focusing units for transmitting said focused image to said photoelectric conversion unit; andwherein said optical device additionally includes a selecting unit located upstream of said light-reflecting unit for interrupting optical paths of said plurality of focusing units except a selected one of said focusing units so that only said focused image from said selected focusing unit reaches said photoelectric conversion unit to perform said specific resolution.
