Abstract

시계 검출 및 비에 의한 흐림 검출이 동시에 가능한 센서가 기재된다. 광은 윈도우 글라스 내부에 밀봉되어, 일부분이 윈도우 글라스 내부에서 반사되어, 일부분이 윈도우 글라스로부터 출사되고, 윈도우 글라스의 외측에 산란되도록 되어 있다. 반사된 부분에서는 비에 의한 흐림이 검출되고, 윈도우 글라스쪽으로 복귀된 산란된 부분에서는 거리가 측정되며, 그 때, 양쪽 부분은 밀봉기구 및 수광기를 사용하여 검출된다.

Description

시계 검출 및 비에 의한 흐림 검출용 센서(Detection of visual range and detection sensor for clouding by rain)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 기본원리를 도시한 도면, 제2도는 프레넬렌즈의 일예를 도시한 도면, 제3도는 수신광로의 광학적 분리를 도시한 도면, 제4도는 변조 및 원상회복용 블록접속도를 도시한 도면.

Claims (7)

  1. 광원의 광이 윈도우 글라스 내부에 밀봉되어 있어, 그 일부분이 윈도우 글라스의 내부에서 반사되어, 비에 의한 흐림 측정을 위해 평가되도록 된 광원과, 출사매질을 통해, 윈도우 글라스로부터 광이 안내되는 센서를 갖는 수광기가 구비된 자동차내에서 시계 검출 및 비에 의한 흐림 검출용 센서에 있어서, 비에 의한 흐림이 없는 윈도우 글라스인 경우라도 출사되는 광의 부분은 시계의 검출을 위해 평가되고, 윈도우 글라스쪽으로 되돌아간 산란광은 출사매질을 통해 수광기에 안내되도록 된 것을 특징으로 하는 시계 검출 및 비에 의한 흐림 검출용 센서.
  2. 제1항에 있어서, 광은 미리 설정할 수 있는 소정각도를 윈도우 글라스 내부에 밀봉되는 것을 특징으로 하는 시계 검출 및 비에 의한 흐림 검출용 센서.
  3. 제2항에 있어서, 출사매질로부터 도래한 광은 산란광 및 반사광으로 분리되는 것을 특징으로 하는 시계 검출 및 비에 의한 흐림 검출용 센서.
  4. 제1항 내지 제3항 중 어느 한 항에 있어서, 감도의 증폭을 위해, 산란광 및 반사광이 촛점화되는 것을 특징으로 하는 시계 검출 및 비에 의한 흐림 검출용 센서.
  5. 제1항 내지 제4항 중 어느 한 항에 있어서, 송신광빔을 공급하는 광원은 변조되는 것을 특징으로 하는 시계 검출 및 비에 의한 흐림 검출용 센서.
  6. 제1항 내지 제5항 중 어느 한 항에 있어서, 광원의 변조는 짧은 펄스에서의 펄스변조인 것을 특징으로 하는 시계 검출 및 비에 의한 흐림 검출용 센서.
  7. 제1항 내지 제5항 중 어느 한 항에 있어서, 변조에는 연속파 진폭변조 또는 의사(擬似)랜덤 2진 변조가 선정되는 것을 특징으로 하는 시계 검출 및 비에 의한 흐림 검출용 센서.
