ABSTRACT:
An optical device for measuring and inspecting a physical and optical characteristic of an object. In the preferred embodiment, the optical device comprises a light source emitting a beam of light rays along an optical axis, a light-sensitive electronic device, preferably a charge-coupled device, positioned along the optical axis converting an image formed from the beam of light rays being reflected from the object into an electrical signal. An image rotating device, preferably a Dove prism, is positioned along the optical axis between the object and the light-sensitive electronic device. A rotating device rotates the image rotating device at an angle of rotation. The rotating device, preferably a d-c step motor, converts the angle of rotation of the image rotating device into an electrical signal. The angle of rotation of the image rotating device is based on a step position of the d-c step motor. The optical device determines physical and optical characteristics of the object based on the strength of the electrical signal from the light-sensitive electronic device and the electrical signal from the d-c step motor.
