ABSTRACT:
A new method and electronic circuit are provided to prevent image creep in automated centrifuges. The method and circuitry automatically substract a fixed time delay, which is associated with the strobe detection and firing circuitry, from a longer variable time period, which is inversely proportional to the rotational speed of the centrifuge, to thereby delay the flash of the strobe by a time inversely proportional to centrifuge rotation speed.
