Abstract: front page image
(EN)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.
(FR)La présente invention concerne un dispositif et un procédé d'émission et de réception de lumière, qui délivrent en sortie la puissance d'une impulsion optique partielle de sorte que sa puissance soit différente de celle d'une autre impulsion optique, de manière à recevoir la lumière réfléchie, et qui identifient si un objet, qui est indétectable à l'aide de la lumière réfléchie d'une impulsion optique émise avec une puissance relativement faible, est détecté à l'aide de la lumière réfléchie d'une impulsion optique émise à l'aide d'une puissance relativement élevée, de manière à ajuster la puissance d'une impulsion optique à émettre par la suite. Par conséquent, l'efficacité de détection peut être maximisée à l'aide d'une faible puissance tandis que les exigences en termes de sécurité pour les yeux sont satisfaites.
(KO)본 발명은 광 송수광 장치 및 방법에 관한 것으로서, 일부 광 펄스의 파워를 다른 광 펄스의 파워와 다르게 출력하여 반사광을 수광하고, 상대적으로 작은 파워로 출력된 광 펄스의 반사광을 이용해 감지하지 못하는 물체가 상대적으로 큰 파워로 출력된 광 펄스의 반사광을 이용해 감지되는지 확인하여, 이후 출력할 광 펄스의 파워를 조정한다. 이를 통해 이를 통해 눈 안전(eye safety) 조건을 충족하면서 저전력을 이용해 감지 효율을 극대화할 수 있다.
