Abstract
The principle of a shooting positions measurement system with laser illumination is introduced. A narrow band-pass filter is used to suppress background radiation except the laser band for detecting small, high-speed, dark objects. The maximal angle of the entrance ray is limited in the case of using the narrow band-pass filter, so different designs of optical systems with a wide field of view are discussed. The result of telecentric objective with 54° field of view and a relative aperture 1/2 is given.
