Method of making a light reflector

摘要

An improved microminiature radiation reflector is formed in a silicon support body with a fabricated cantilever member extending over a cavity that has been etched in the support body. The cantilever member has a reflection surface for reflecting incident radiation to a first position when the cantilever member is not deflected. An electromagnet is formed in the silicon support body adjacent the free end of the cantilever member for deflecting the cantilever member into the cavity of the support body so as to cause incident radiation to be reflected to a second position. An array of radiation reflectors is also disclosed for forming images from electrical signals applied to the electromagnets of selected ones of the radiation reflectors as a function of the position of their reflected radiation in the to be formed image.
