A low-cost hematology analyzer that used a uniform velocity, laser scanning beam to scan a centrifuged blood tube was developed. The method involved rotating a scanning mirror which would be used to measure the band lengths of the blood tube. An inexpensive motor with the best linearity and repeatability was employed for the analyzer. Tests scans of the test tool were conducted for each motor and the known distance between segments was compared to the acquired and calculated distances. The floppy-disk drive motor with a mirror mounted on its shaft was found to be the most efficient among other motors.
