WINDOW OPTICAL SECURITY SYSTEM THROUGH NET WEAVED BY PLASTIC OPTICAL FIBER

摘要

PURPOSE: Provided is a window optical system through a net weaved by plastic optical fiber(POF) which measures and calculates the intensity of an optical signal transmitted through a POF net to judge invasion so that it shows excellence in workability and an economic side. CONSTITUTION: The window optical system through the net weaved by plastic optical fiber(POF) comprises the parts of: single or multiple(107, 108) light sources; a POF net(106) which is weaved by single or multiple plastic optical fiber through single or multiple light sources; a control part(104) which includes single or multiple optical detectors(109, 110) to detect the intensity of the optical signal transmitted through the POF net and calculates the output of the optical detector to judge invasion; an external device(105) which treats or informs the signal from the control part; and a nut and a frame tools which include the function for preventing from being taken to pieces.
