Abstract
Systems and methods for identifying an interchangeable lens in a vision system having a controllable light source, a camera, and the lens to be identified. Light provided by the light source is transferred to the camera by the lens to be identified. The amount of light transferred to the camera for a particular reference configuration of the vision system depends distinguishably on the characteristics of the lens to be identified. A camera output is measured for a desired light source setting and the desired light source setting and associated measured camera output are compared with stored lens identification calibration data. The stored lens identification calibration data is obtained by measuring the camera output for a plurality of lenses using a plurality of light source settings. In various exemplary embodiments, the light transferred from the light source to the camera is reflected and/or backscattered light from the lens to be identified.
