Abstract: A long range eye-safe laser radar (LADAR) system for use in an environment where real-time non-cooperative identification of an object is required. In particular, a laser beam is aimed at an object, the laser energy reflected from the object is collected by a detector array for use in generating a composite of both a high resolution 3-Dimensional (3D) shape of the object and the object's high resolution micro-Doppler vibration spectrum, a characteristic of the object as unique as a fingerprint. The composite is then used to automatically identify the object by comparison to a database of similar composite sets of 3D shape and vibration spectrum information with the results of the identification conveyed to the user.

Abstract: The present invention relates generally to a long range eye-safe laser radar (LADAR) system for use in an environment where real-time non-cooperative identification of an object is required. In particular, a laser beam is aimed at an object, the laser energy reflected from the object is collected by a detector array for use in generating a composite of both a high resolution 3-Dimensional (3D) shape of the object and the object's high resolution micro-Doppler vibration spectrum, a characteristic of the object as unique as a fingerprint. The composite is then used to automatically identify the object by comparison to a database of similar composite sets of 3D shape and vibration spectrum information with the results of the identification conveyed to the user.

Abstract: A starting device for a sealed, cross-flow gas laser for operating at least wo electric discharges simultaneously in a single laser cavity using primary fins between the cathodes and anodes of the cavity as intermediate electrodes. A series of high voltage relays and resistors are placed in parallel with the discharge path between adjacent fin electrodes and by switching out pairs of relays current is coupled to the discharge path, one fin at a time.
