Claim 10:
11. A sensor apparatus comprising:
a laser ranging device that scans a predetermined scan range with laser light such that at least a part of the laser light passes through a region including a predetermined detection region;
a reflection mirror that reflects at least a part of the laser light to a direction not parallel to an incident direction and is provided so that the laser light occurring after reflection passes through the detection region;
an object detector that performs first detection by using the laser light occurring before reflection by the reflection mirror and second detection by using the laser light occurring after reflection by the reflection mirror in parallel planes on an object; and
a shield object distinguisher that distinguishes a shield object from the object by comparing the scan range in the first detection with the scan range in the second detection.
