| description | To provide an optical sensor having a high detection precision.SOLUTION: An optical sensor for detecting a target Tr by receiving reflection beams from the target Tr for irradiation beams IB applied to a detection area Ad includes: a light emitting unit for individually projecting the irradiation beams IB from multiple arranged dot light sources 31; a light reception unit for detecting the target Tr by allowing multiple light-receiving pixels arranged in accordance with the respective dot light sources 31 to individually receive reflection beams through a light reception optical system; and a control unit that performs thinning control of the number of the dot light sources 31 for projecting the irradiation beams IB toward a short-distance area Adc in which the light-receiving unit detects the target Tr in a determination distance range in which a near point regarding field depth of the light reception optical system becomes a determination boundary in the detection area Ad as compared with the time when the target is detected in the short-distance area Adc, and allows the light-receiving unit to execute re-detection in the short-distance area Adc.SELECTED DRAWING: Figure 9
【課題】検出精度の高い光学センサを提供すること。【解決手段】検出エリアＡｄへ照射した照射ビームＩＢに対するターゲットＴｒからの反射ビームを受光することにより、ターゲットＴｒを検出する光学センサは、複数配列されたドット光源３１から個別に照射ビームＩＢを投光する発光ユニットと、各ドット光源３１と対応づけて複数配列された受光画素が受光光学系を通して反射ビームを個別に受光することによりターゲットＴｒを検出する受光ユニットと、検出エリアＡｄのうち、受光光学系の被写界深度に関する近点が判断境界となる判断距離範囲内において受光ユニットがターゲットＴｒを検出した近距離エリアＡｄｃに向けて、照射ビームＩＢを投光させるドット光源３１の数を、近距離エリアＡｄｃでの検出時よりも間引き制御して、近距離エリアＡｄｃでの再検出を受光ユニットに遂行させる制御ユニットとを、備える。【選択図】図９ |
