About:
Technology advancements in ultrasonics and in micro and nanotechnology have given rise to new optical methods to make high frequency (HF) and ultra high frequency (UHF) measurements of mechanical vibrations. Laser-based, non-contact optical testing is the best choice since it avoids mass loading from direct contact. Ultrasound is used in production processes, in medical sensors and dental scalers, in nebulizers for drug delivery and in parking sensors for our cars.
