A video measurement system includes an imaging system, a reticle projector for projecting an image of a reticle through the imaging system onto the test object, and a camera for capturing images of the test object together with the reticle image projected onto the test object through the imaging system. A selective reflector reflects the reticle image into the camera from a position along the imaging system in advance of the test object. A mode selector is operable in a first mode for directing the reticle image to the test object and from the test object to the camera and is operable in a second mode for directing the reticle image to the selective reflector and from the selective reflector to the camera.
