LaserSpeed Terminology

LaserSpeed is a laser-based, non-contact measurement system that is often searched using a variety of terms. It uses a technology known as Laser Doppler Velocimetry (LDV) to measure the length and speed of products. LDV uses the Doppler shift in a laser beam to measure the velocity of moving transparent, semi-transparent, or opaque reflective moving surfaces. Depending on the industry, the LaserSpeed measurement system is often termed as a non-contact length and speed encoder, non-contact length and speed gauge, or simply non-contact encoder or non-contact gauge. Many of these non-contact length and non-contact speed measurement terms have become synonymous with the LaserSpeed product name.

LaserSpeed offers a number of significant advantages over contact-type measurement methods, such as mechanical contact encoders, rotary encoders, tachometers, and shaft encoders.
