Abstract:

The Note presents the design, detection capabilities, and testing of a wide-angle skylight optical screen primarily intended for use in the measurement of projectile velocity and retard on outdoor ranges. Semiconductor electronics have enabled the construction of a unit ideally suited for use in remote areas where it is advantageous to employ a light, easily portable instrument designed for operation from either a low voltage battery source or 100 VAC power line.
