ABSTRACT:
An adaptable, accurate, high resolution centrifuge core measuring method using a single strobe flash per measurement uses a microprocessor controller to control the measuring method, not a computer. The controller, not the camera clock, decides when the camera data should be read. The camera data is read into and stored in the controller, not a computer. The controller reads the camera array, controls centrifuge speed, determines alignment of the proper catch tube, flashes the strobe, determines lapse time, rereads the pixels, stores and analyzes the pixel information and the other steps of the method. The controller is capable of operating in many modes. But at any point, for operator intervention the controller is adapted to let the computer intervene.
