I am looking for a sensor that I can buy or make from scratch to sense displacement of a very light object. The sensor must be non-contact, and the item cannot be weighted down. Ideally the technology would be optical with a sensor positioned between 1.0 and 2.0 mm away from the object that is moving past the sensor. The environment is indoor ambient, relatively clean. The motion is about 20 mm., and it need not be tracked for direction. I need high bandwidth - 50,000 samples per second. Absolute position accuracy is not needed - I just need to measure acceleration. And the moving part cannot be weighed down by an accelerometer.
