Title:
OPTICAL DEVICE, ON-VEHICLE SYSTEM AND MOBILE DEVICE
Document Type and Number:
Japanese Patent JP2021181892
Kind Code:
A
Abstract:
To provide an optical device, an on-vehicle system and a mobile device which are capable of determining credibility of an outputted signal.SOLUTION: An optical device 1 includes a deflection part 30 which scans an object by deflecting illumination light from a light source part 10 and at the same time deflects catoptric light from the object, a light guide part 20 which introduces the illumination light from the light source part 10 to the deflection part 30 and at the same time introduces the catoptric light from the deflection part 30 to a first light receiving element 43, a reflection part 71 which reflects first light which is a part of the illumination light from the deflection part 30 to be made incident on the deflection part 30 again, a filter 41 which is disposed between the reflection part 71 and the first light receiving element 43 and makes light with specific wavelength band penetrate and a control part which determines whether or not strength of the first light falls within a specific numerical range by using a signal based upon the first light outputted from the first light receiving element 43.SELECTED DRAWING: Figure 1
