Laser radar eye hazard considerations.

An analysis is made of the eye hazard posed by laser radars and the methods for reducing this hazard. The particular situation analyzed here is that of a person at target range being exposed to a single pulse by accidentally looking directly into a laser beam. Curves are presented which show where the safe and hazardous radar regions occur. These curves show that by following a philosophy of transmitting no greater intensity than is necessary to achieve a given level of radar performance, the eye hazard can be considerably reduced.
