Ultra-sensitive Speckle Analyzing Sensor
Low-cost optical sensor detecting tiny vibrations, heat, or motion changes across industries.
Researchers at Purdue University have developed a low cost ultra-sensitive speckle analyzing sensor. This technology assembly comprises a probing laser, remote object of interest, scattering layer, and a detector. This additional scattering layer offers enhancements in sensitivity by a few orders of magnitude. Some of the physical or optical changes in the remote object that can be picked up with high sensitivity include vibration, heat expansion, translation, deformation, and rotation. This technology helps a wide range of industries that use optical sensors, such as automotive, environment control, security and monitoring, and material science research and development.
