Title:
SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/014784
Kind Code:
A1
Abstract:
This sensor device is so configured as to reflect, by means of an optical mirror, a laser beam for detection to the side of a space to be detected, said laser beam being emitted from a laser device for detection, and to detect, by means of a light detecting unit, the laser beam reflected on the side of the space to be detected. The sensor device includes a half mirror, and the half mirror is disposed such that a part of the laser beam inputted to the half mirror is reflected and the rest is passed through. Between the optical mirror and the half mirror, the optical axis between the laser device and the optical mirror accords with the optical axis between the optical mirror and the light detecting unit.
