JLA Vol:5 Iss:1 (Tutorial Guide: Laser Measurement Techniques Guide For Hazard Evaluation. Part 1)
Authors:
Terry Lyon
Laser Microwave Division, U.S. Army Environmental Hygiene AgencyA tutorial guide is presented to provide uniform guidance when performing radiometric measurements upon laser systems to perform a hazard evaluation. This guide was requested by and presented to the Department of Defense (DOD) Laser System Safety Working Group (LSSWG) to serve as a standardized method when performing hazard evaluations primarily upon tactical and training military laser systems including laser rangefinders and designators. Technical information is provided in detail to select a suitable detector, preform radiometric measurements, assess laser system pointing errors, calculate laser pr...

Laser Engineering Group, Department of Engineering, The University of Liverpool, Liverpool L69 3GH, United KingdomSlate is a natural stone which has the characteristic that shows a well-developed defoliation plane, allowing to easily split it in plates parallel to that plane which are particularly used as tiles for roof building. At present, the manufacturing of slate is mostly manual, bein...

Beckman Laser Institute, Irvine, California 92715 U.S.A.Lasers are assuming an increasingly important role in surgical procedures. However, several studies have shown that the smoke produced by laser‐tissue interaction is an airway irritant. Preliminary studies in our laboratories have shown that potentially hazardous chemicals, including benzene, formaldehyde and acrolein are present in the smoke plume resulting from CO2 and Nd:YAG laser interaction with animal tissue, even at low power densities. Since these chemicals are classified a...

A. W. PalmerAn experimental investigation of three different types of highly birefringent fiber sensor element configured as a force and a displacement sensor is described. From the coupling of power between the two eigenmodes, the magnitude of the force and the position of the coupling point can then be determined using ‘white‐light interferometric’ techniques.
