Abstract

측정 대상물이 고온화하여 발광하는 것일지라도, 그 측정 대상물 까지의 거리를 구할 수 있도록 한다.Even if the object to be measured emits light at a high temperature, the distance to the object can be determined.

측정 대상물(7)에 빛을 투사하고, 상기 측정 대상물(7)로부터 반사한 빛을 수광하고, 삼각측량 방식에 의하여 그 측정 대상물(7)까지의 거리를 측정하는 거리측정 방법에 있어서, 상기 측정 대상물(7)에 투사하는 빛은 발광할 정도로 고온화한 해당 측정 대상물(7)이 발하는 빛 보다도 단 파장의 빛이고, 상기 측정 대상물(7)로부터 반사한 빛을 상기 단 파장의 빛만을 통과시키는 필터(21)에 통과시켜 수광한다.The distance measuring method which projects light to the measurement object 7, receives the light reflected from the measurement object 7, and measures the distance to the measurement object 7 by a triangulation method. The light projected onto the object 7 is light of a shorter wavelength than the light emitted from the measurement object 7 heated to a high temperature so as to emit light, and a filter that passes only the light of the short wavelength through the light reflected from the measurement object 7. Pass light through (21).
