Lasers track faster profile line speeds. (Keeping Up with Extrusion).The latest generation of a laser-based speed sensor Speed sensors are machines used to detect the speed of an object, usually a transport vehicle. They include:
LDV Light Duty Vehicle LDV Laser Doppler Velocimeter LDV Local Defence Volunteers (Afterwards Home Guard, UK) LDV Limited Dependent Variable LDV Laser Doppler Vibrometers LDV Leyland Daf Vehicles (laser doppler velocity) sensor from Canon U.S.A., Inc.'s Semiconductor Div., Lake Success, N.Y, has a velocity range from 50 to 5000 mm/sec or up to 1000 ft/min vs. 100 ft/min before. It measures profile speeds using two convergent laser beams and is insensitive in·sen·si·tive adj. 1. Not physically sensitive; numb. 2. a. Lacking in sensitivity to the feelings or circumstances of others; unfeeling. b. to profile size, density, or color. In fact, it can measure profiles with reflectivity re·flec·tiv·i·ty n. pl. re·flec·tiv·i·ties 1. The quality of being reflective. 2. The ability to reflect. 3. as low as 20%.
