This article describes the specifications of two portable laser systems and their uses at crime scenes.
Abstract
The Vector-BLS ballistic laser, which was developed by the CAO Group Inc., located in West Jordan, UT, can display a bullet trajectory with a level of brightness that makes visualization and photographic documentation easier than with traditional methods. The Vector system operates with built-in 12-volt rechargeable batteries that power an adjustable beam range output of 0.1 to 300 milliwatts at 532 nanometers. It has 100 times the power output of standard red lasers. In addition, it can be operated while attached to an external power supply. It has a range of 1,000 yards in displaying trajectory and terminal points for bullets, a tripod and leveling mechanism for stability and accuracy on slopes and uneven ground, complete angle control, vertical ranges of either 360 degrees or 400 gradians, and an adjustable sighting scope to locate a distant point or target. Another portable laser system called Reveal, developed by the Newport Corp., of Irvine, CA, improves the identification of evidence at crime scenes. Reveal is a portable, continuous wave, laser-based system that uses thin-disk lasers. Along with the improved identification of latent fingerprints, Reveal exposes traces of blood, semen, saliva, sweat, bone, teeth, and skin. In revealing such evidence, it is not hindered by surfaces such as fabric or dry and uneven surfaces. The authors provide examples of evidence detected by Reveal that traditional light sources missed.
