Patent ID: 7812932

Claim:
A test station for testing an ability of a laser range finder to determine a distance to a first range target, the test station comprising: a frame; a holder supported by the frame, the holder supporting a laser range finder being tested, the laser range finder having an alignment source and a range source aligned to the alignment source; an eyepiece supported by the frame; and an optical system supported by the frame, the optical system including a first reference plane in which the alignment source and the range source are aligned to a first axis, a second reference plane in which the eyepiece is centered on a second axis contained in the second reference plane, and a third reference plane which intersects the first range target along a third axis contained in the third reference plane, the optical system including a first portion which receives light from the alignment source of the laser range finder along the first axis and redirects it from the first reference plane to the eyepiece along the second axis in the second reference plane, a second portion which receives light from the first range target along the third axis in the third reference plane and redirects it to the eyepiece along the second axis in the second reference plane; and a third portion which aligns the range source of the laser range finder along the first axis with the first range target along the third axis.
