| description | PROBLEM TO BE SOLVED: To provide a photoelectronic sensor where detection of an object and distance measurement when there is turbidity are improved.SOLUTION: A photoelectronic sensor (10) for detection of an object and distance measurement in a monitoring area (18) is presented. The photoelectronic sensor (10) is provided with: a projector (12) for projecting the projection beam (14); a deflection part (16) which can rotate so as to periodically deflect the beam (14); a light receiver (24) for generating a light-receiving signal from a beam (20) which is diffused and reflected in the monitoring area (18); an AD converter (30) for sampling the light-receiving signal; and an evaluation part (32). On the basis of the light-receiving signal, a distance to the object is measured by using a light propagation time method, and turbidity is measured as well. The evaluation part (32) measures the degree of turbidity with respect to the turbidity in the direction of the projection beam (14) according to an angle, a distance from the same signal as the light receiving signal to be a target of turbidity measurement is measured, and the turbidity according to the angle is considered when measuring the distance. |
