Contact fiber optic impact sensor

摘要: A fiber optic sensor is provided which useful for detecting impact, pressure or other forces, and has particular application in the presence of a foreign object an electronically operated vehicle window including motor, frame pane movable between open closed position. The comprises having one end connected to light source, with being detector. In optic, there located sensing portion preferably so as modulate traveling optical path fibre response detection comes into contact therewith. further signal propagating means transmitting motor when modulated stop reverse motor.
