본 발명을 첨부 도면에 의해 상세히 설명하면 다음과 같다. 도 1은 본 발명의 레이저발생기를 이용한 구조물 변형감지 장치 기본형식,The present invention will be described in detail with reference to the accompanying drawings as follows. 1 is a basic form of a structure deformation detection device using the laser generator of the present invention,

도 2는 다른 실시례의 본 발명의 레이저발생기와 반사경을 이용한 구조물 변형감지 장치이다.2 is a structure deformation detection apparatus using a laser generator and a reflector of the present invention according to another embodiment.

본발 명은 레이저발생기(10)가 한편에 설치되고 중간에 핀홀판(20)이 설치되며, 반대편에는 타켓(90)이 설치되어 레이저발생기(10)에서 발생되는 레이저광이 핀홀(30)을 거쳐서 타켓(90)에 수렴되는 여부에 따라서 구조물(100)의 변형을 감지하게 된다. In the present invention, a laser generator 10 is installed on one side and a pinhole plate 20 is installed in the middle, and a target 90 is installed on the opposite side, so that the laser light generated from the laser generator 10 passes through the pinhole 30 to the target. The deformation of the structure 100 is sensed according to whether or not it converges to 90.

그러므로 구조물이 변형되어 레이저광의 방향이 달라지면 구조물에 부착된 핀홀(30)을 통과하는 레이지광의 양이 차이가 난다. 그러므로 타겟에 도달하는 레이저광의 광도가 감소되거나 타겟의 중심을 벗어나게 된다.Therefore, when the structure is deformed and the direction of the laser light is changed, the amount of laser light passing through the pinhole 30 attached to the structure is different. Therefore, the luminous intensity of the laser light reaching the target is reduced or it is off the center of the target.

다른 실 사례로서 상기 레이저발생기(10)와 타겟(90) 사이에 반사판(50)을 설치하여 넓은 면적을 감지할 수 있게 된다.As another practical example, by installing the reflector 50 between the laser generator 10 and the target 90, it is possible to detect a large area.

따라서 본 발명은 레이저광의 직진성을 이용하여 구조물의 변형을 필요시 수시로 용이하고 간단하게 감지하는 현저한 효과가 있다.Therefore, the present invention has a remarkable effect of easily and simply detecting the deformation of a structure when necessary by using the linearity of the laser light.
