Abstract: front page image
(EN)Disclosed are a distance measurement system using a tunable laser and distance modulation and a distance measurement method using the same, wherein the distance measurement system comprises a laser oscillation part, a diffraction guide, a measurement unit, and a measurement part. The laser oscillation part generates continuous light having different wavelengths. The diffraction guide is disposed to be spaced a predetermined distance apart from the laser oscillation part. The measurement unit includes a measured object reciprocating between a first location spaced a first distance apart from the diffraction guide and a second location spaced a second distance apart from the diffraction guide. The measurement part receives coherent light between the measurement unit and the diffraction guide according to the occurrence of the continuous light.
(FR)L'invention porte sur un système de mesure de distance utilisant un laser accordable et un procédé de mesure de distance et de modulation de distance l'utilisant, le système de mesure de distance comprenant une partie d'oscillation laser, un guide de diffraction, une unité de mesure, et une partie de mesure. La partie d'oscillation laser génère une lumière continue présentant différentes longueurs d'onde. Le guide de diffraction est disposé de manière à être espacé d'une distance prédéterminée depuis la partie d'oscillation laser. L'unité de mesure comprend un objet mesuré en va-et-vient entre un premier emplacement espacé d'une première distance du guide de diffraction et un second emplacement espacé d'une seconde distance du guide de diffraction. La partie de mesure reçoit une lumière cohérente entre l'unité de mesure et le guide de diffraction selon la présence de la lumière continue.
(KO)튜너블 레이저와 거리 변조를 이용한 거리 측정시스템 및 이를 이용한 거리 측정방법에서, 상기 거리 측정시스템은 레이저 발진부, 회절가이드, 측정유닛 및 측정부를 포함한다. 상기 레이저 발진부는 파장이 서로 다른 연속광을 발생시킨다. 상기 회절가이드는 상기 레이저 발진부와 소정거리 이격되도록 배치된다. 상기 측정유닛은, 상기 회절가이드로부터 제1 거리만큼 이격된 제1 위치와 상기 회절가이드로부터 제2 거리만큼 이격된 제2 위치 사이를 왕복하는 측정물을 포함한다. 상기 측정부는 상기 연속광의 발생에 따라, 상기 측정유닛과 상기 회절가이드 사이에서 간섭된 광을 수광한다.
