Abstract
PURPOSE: To enable to make range finding for a given range with a simple constitution, by receiving the scattered light from the object emitted with light beam via the collective lens at the location apart from the beam light.
CONSTITUTION: When the measured substance 3 is emitted with the laser beam 2 from the light source 1, the photo spot 6 is formed on the object 3. The reflection scattered light from the object 3 by this spot 4 is collected at the collective lens 5 installed at a location apart from the straight line tying the measured object 3 formed by the beam 2 and the light source 1, and when the distance from the measured object is within a given range, it is provided within a plane formed with the beam 2 and lens 5 and it forms its image on the photo electric conversion element 6 providing a plurality of elements in parallel with the lens 5. Accordingly, the range finding such as distance between vehicles for collision prevention can be made with a simple constitution.
