OBJECT DETECTION DEVICE

An object detection device includes an optical fiber at least partially including a sensor optical fiber configured to transmit light with a loss of 0.3 dB/m or more and a light receiving unit configured to receive, from the optical fiber, the light received by the sensor optical fiber. The object d...

Beschreibung
Zusammenfassung:	An object detection device includes an optical fiber at least partially including a sensor optical fiber configured to transmit light with a loss of 0.3 dB/m or more and a light receiving unit configured to receive, from the optical fiber, the light received by the sensor optical fiber. The object detection device detects an object based on an intensity of the light received by the light receiving unit. The sensor optical fiber may have a core, the outer periphery of which is at least partially exposed. The outer periphery of the core may have an uneven structure provided thereon, the uneven structure having a size of 1/100 or more and 1/10 or less of a wavelength of the light received by the light receiving unit. In addition, the length of the sensor optical fiber may be ten times or more the wavelength of the light received by the light receiving unit.
