Remote velocity detection
Remote velocity detection
(OP)
I would like to measure the velocity of a surface 0-150mm/s with a non contact sensor and a high refresh rate, 10kHz. I would like to output signal to oscilloscope or PC, pulse or analogue signal would do.
Sensor can be close to surface and I can can mark the surface with lines like an encoder track. Lines would have to be <0.2mm.
I have tried a high speed contrast laser sensor but it was too slow even at 0.05ms switching time.
I thought of high speed opto-switch with microscope and even optical mouse sensor technology.
I cant find reflective encoder technology that doesn't require really high accuracy between surface and sensor.
Know of any suppliers in the industry that may have a solution?

Perhaps you need to consider something like a linear velocity transducer: http://www.transtekinc.com/linear_vel.htm
