| Abstract | The device presented herein is an oscillator which outputs a square wave proportional in frequency to the input to the oscillator. That is, if the input is F1 and the output is F0, the relationship between the two is given by:
F0= F1 * K Where 0.95 < K < 1.05
The oscillator is meant to be used with an optical pickup and a stroboscope to view high speed rotors. (See Fig. 1) If K is set to 1, the rotor appears to be stationary. If K is less than 1, the rotor will appear to slowly rotate in the actual direction of rotation. If K is greater than 1, it will appear to be the opposite. |
