Patent Searching and Data


Title:
LASER LIGHT SEARCH SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/044411
Kind Code:
A1
Abstract:
Provided is a laser light search system whereby a search object that is present on land or in water can be accurately searched for using laser light from the air. An optical tag 40 of a laser light search system 10 is a retroreflective light-reflecting tag for reflecting reflected laser light Lr toward a laser light transmission/reception device, and imparts identification information set in advance which relates to a person (search object) 32 to the reflected laser light Lr, and the laser light search system 10 includes a computational processing device for receiving the reflected laser light Lr and extracting the identification information from the received reflected laser light Lr. The reflected laser light Lr is reflected from the abovementioned retroreflective light-reflecting tag, and has a relatively high reception gain, and it is therefore possible to accurately search for a person (search object) 32 present on land or in snow or water. Information for identifying the person (search object) 32 is included in the reflected laser light Lr and can be individually extracted.
