MEMS-Based High Throughput Screening

From KineticSystems/GaGe
 

 
The customer needs to do frequency analysis to determine the resonant frequency of an oscillating micro-fabricated device. They will use a Laser Doppler Vibrometer to monitor the physical oscillation. This is an instrument that looks at the light reflected from the surface of a moving part to determine the velocity
