An ultra-high-precision frequency-shifting Laser Doppler Velocimeter/Anemometer (LDA/LDV) sold by Measurement Science Enterprise, Inc. I'm responsible for the optical design, which started as a 3D layout in SolidWorks and was then manually converted to ZEMAX format for optimization and performance prediction. The probe is fully integrated, that is, all signal processing happens inside the box; it requires only power and a USB connection to a computer for storing results.
