Abstract
Methods and apparatus for effective investigational feature recognition in laboratory samples in optical equipment. Pixelization permits investigational feature recognition at the digitized waveform level instead of at the image level. Pixelization can be used with a bio-disc and its related disc drive assembles. The analog signal from the drive's detector is sampled into a digital waveform. Patterns in the waveform that match the features in the laboratory samples are counted. Synchronizing the sampling rate with the bio-disc drive clock cycle is provided. Other embodiments include calibrating the sampling rate using wobble grooves, pit fields, and an external sampling card with its associated counting software.
