ABSTRACT:
A mechanism for moving and positioning a light source so that its light impinges a target as it moves on or off axis of an optical system. A detector may receive scattered light at a same position whether the light impinging the target is on or off axis due to, for example, a telecentric optical system. Further, the light may be positioned so that the detector is maximally impinged with scattered light. An output may go to a processor that sends a signal to the light source to move the emitted light so as to continually impinge the target as it moves on or off axis. An array of light sources may used in lieu of the moving light source. To move the light beam, another light at another position in the array may be selected to replace a previously selected light source.
