とする距離検出装置。A reflected spot of infrared light projected from a projector toward a distance measurement object and reflected by the distance measurement object is incident on a location where the light is imaged according to the distance of the distance measurement object based on the parallax with the projector. Spot light level. In a distance detection device that uses a triangulation method to measure distance by arranging a semiconductor optical position detector that continuously detects the position of the target, the object to be measured gradually moves from infinity to near the front of the light-receiving surface of the semiconductor optical position detector. A distance detection device characterized in that triangular prisms are arranged in a manner that the wall thickness becomes gradually thinner along the direction in which the position of the reflected spot light changes as the distance approaches.
