摘要： A three dimensional true color holographic imaging system using three primary color Fresnel-Zone-Pattern laser generators combined as a single beam that scans the target and the reflections of which are sensed simultaneously by a single electronic detector. The detector signals corresponding to each generator are then separated electronically and independently recorded.

摘要： A system and method for registering 3D data sets is disclosed based on manual fiducial selection. The technique is useful in imaging obscured targets with 3-D imaging laser radars. For such an exemplary method, which defines a three-dimensional linear shift vector for each data voxel, four fiducials are required to completely define the mapping for a 3D space. An exemplary registration algorithm as disclosed provides an approach to automatically make fine adjustments to the 3D data registration. The tedious technique of shifting data sets relative to each other, in many degrees of freedom, is eliminated. Instead, a fine adjust is applied to the digital mapping function, through fiducial perturbation.

摘要： A YAG/Nd:YAG block where an Nd:YAG block ends in a peak integrated inside a YAG block. The YAG block has reflective surfaces positioned at 45° to one another. The angled reflective surfaces serve as a “mirror” within the laser cavity to effectively increase the length of the cavity by a factor greater than 2. Fused to the output end of the laser cavity are a polarizer, an active/passive Q-switch, a one quarter waveplate and an output coupler. In operation, the laser cavity is pumped either from the side or the end of the cavity. The optical components of the present invention are bonded to form one optical ‘block’. All the components are prealigned during the crystal manufacturing process to form the optical laser cavity. The width of the cavity should be selected such that nearly all of the laser diode pump output is absorbed by the cavity.
