Title:
LIGHT TRANSMITTING AND RECEIVING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/079921
Kind Code:
A1
Abstract:
The present invention relates to a light transmitting and receiving device and method, which output the power of a partial optical pulse such that the power thereof is different from that of another optical pulse, so as to receive reflected light, and identify whether an object, which is undetectable using the reflected light of an optical pulse outputted with relatively low power, is detected using the reflected light of an optical pulse outputted with relatively high power, so as to adjust the power of an optical pulse to be output thereafter. Therefore, detection efficiency can be maximized using low power while eye safety requirements are satisfied.
