LASER BASED INSTRUMENTATION

Laser is an excellent tool for measurement application. It offers the advantage of non-contact, non-destructive and fast measurement. Also it is more suitable for remote measurement in toxic and hazardous environment. Laser based Instrumentation deals with the design & development of instruments that use laser for sensing the physical parameter or variable. They have Industrial as well as scientific applications. In this article, Laser based instruments for diameter measurement, Surface Roughness measurement, Projectile Velocity measurement and Flow visualisation are discussed which are developed in-house.
