OPTICAL PATH SENSING APPARATUS FOR OPTICAL SYSTEM

摘要

PURPOSE: An optical path sensing device for an optical system is provided to allow a user to recognize the path of light transferred in an optical system with a naked eye by vibrating or rotating an optical sensing member. CONSTITUTION: An optical path sensing unit(120) is arranged between a transmitting unit(110a) and a receiving unit(110b) and senses light being projected. The optical path sensing unit comprises an optical sensing member(122) which is formed of a transparent film coated with a fluorescent or phosphorescent material, a vibrating member which is connected to the optical sensing member through a connector connected to the bottom of the optical sensing member and vibrates the optical sensing member, and a support member(126) which is arranged in contact with the bottom of the vibrating member and supports the optical sensing member and the vibrating member.
