It is easily the most subjectiveâas well as one of the most controversialâtechniques in the field of forensic anthropology. Despite this controversy, facial reconstruction has proved successful frequently enough that research and methodological developments continue to be advanced.
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term laser originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light coherently, spatia
Laser Radar. A laser radar is a device which uses one of the distance measurement techniques as described above, and scans the direction of the distance measurement in two dimensions. This allows the acquisition of an image, or more precisely a depth profile of some object, as required e.g. in robotics.ome of the most important techniques used for laser distance meters are as follows: 1  Triangulation is a geometric method, useful for distances in the range of ââ1 mm to many kilometers.
