Abstract
A micro-mirror system has a closely spaced array of micro-mirror cells, a calibration timing circuit, and test circuitry. Each micro-mirror cell has a micro-mirror and a timing circuit. The timing circuit controls deflection of the micro-mirror. The micro-mirror is in close proximity with the timing circuit. The calibration timing circuit is like the timing circuits of the micro-mirror cells. The test circuitry tests a time constant of the calibration timing circuit.
