Abstract: A range and bearing-finding system is disclosed. A diverging encoded laser beam is transmitted to a target, and a return reflection of the encoded beam received. The transmitted beam is sampled, and a plurality of predetermined time delays are applied to the sampled laser beam. The sampled laser beam with each of the predetermined time delays is correlated with the return reflection until a sampled laser beam having a time delay providing the highest correlation is found, the time delay indicating laser travel time to and from the target. Range is determined from this time delay. Bearing of the target is found by using a quadrant protector to receive the return reflection. The process for finding bearing uses the correlation process used to find range.

Abstract: Disclosed is a hermaphroditic fiber optic connector having provision for an automatic protective covering for the fiber optic for covering the end at any time that the connector is demated. In one embodiment the connector provides precise positioning of parallel disposed fiber end surfaces with the angle of the end surface being preferably greater than the sum of the Brewster Angle and the Numerical Aperture (NA) of the fiber to assure reflectionless high efficiency transmission.
