Abstract:
An optical switch, comprising:a primary refracting body having a total internal reflecting surface and capable of transmitting optical energy therethrough; first and second collimating lenses coupled to respective surfaces of said primary refracting body; a frustrating refracting body located proximate said total internal reflecting surface and having a mirror; and an actuator, coupled to said primary refracting body and said frustrating refracting body, that drives said frustrating refracting body between an open state, in which a collimated beam emanating from said first collimating lens reflects off said total internal reflecting surface and travels toward said second collimating lens, and a closed state, in which said collimated beam emanating from said first collimating lens reflects off said mirror and travels back toward said first collimating lens.
