Abstract
Laser radar systems include a pentaprism configured to scan a measurement beam with respect to a target surface. A focusing optical assembly includes a corner cube that is used to adjust measurement beam focus. Target distance is estimated based on heterodyne frequencies between a return beam and a local oscillator beam. The local oscillator beam is configured to propagate to and from the focusing optical assembly before mixing with the return beam. In some examples, heterodyne frequencies are calibrated with respect to target distance using a Fabry-Perot interferometer having mirrors fixed to a lithium aluminosilicate glass-ceramic tube.

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application 61 / 728,999, filed November 21, 2012; U.S. Provisional Application 61 / 753,786, filed January 17, 2013; Interest, these applications are incorporated herein by reference. technical field [0003] The present disclosure relates to lidar systems. Background technique [0004] LiDAR systems provide simple, convenient, non-contact measurements that facilitate single-operator object inspection. LiDAR systems are especially useful for applications where large objects such as aircraft, automobiles, wind turbines or satellite components are to be measured. Some conventional lidar systems are described in US Patents 4,733,609, 4,824,251, 4,830,486, 4,969,736, 5,114,226, 7,139,446, 7,925,134, US Patent Application Publication 2011 / 0205523, and Japanese Patent 2,664,399, which are incorporated herein by reference. In these lidar systems, a laser beam is directed and scanned ov...
