Abstract
A laser transmitting and receiving speed and/or range detection device has coaxial internal beam directing and receiving paths for the transmitted and received (reflected) laser energy. A sight is provided having an optical combiner which presents a projected display of the detected speed or range of a target that may be observed by the operator while aiming the device at the target. A telephoto effect is utilized in the projection of the display onto the sight such that the operator need not divert his head from the sight or refocus his eye to read the projected target speed or range.
