摘要： A method for measuring a surface structure of a near-field object is provided. A light source produces at least a first light beam and a second light beam; guiding the first light beam and the second light beam to enter the SIL for interacting with the object surface. This method can be used in, for example, a near-field optical disc storage system, wherein reflection intensities of the first and second light beams are used to measure two distances between the SIL and the optical disc at two positions corresponding to the first and second light beams. A surface structure, such as a tilt angle or an average distance between the disc and the SIL or disc roughness, is obtained by analyzing the above-mentioned positions and distances. The first and second light beams are produced, for example, by a diffraction technology or by a single laser diode with multiple beams.

摘要： A method for measuring the electromotive force of motors is provided. The method enables the motor to rotate in single phase mode, and thereby measures the electromotive force constant of the motor. According to the principles and the method, motors do not have to work in close-loop. Neither encoders for detecting angle displacement or angle velocity are needed for motors, nor the motor impedance or current have to obtain in advance. Compared with the prior art, the disclosed method is more efficiency and economic.

摘要： A sensorless driving method for a brushless DC motor is provided. The time for the motor to rotate an electrical angle 60° is obtained by alternatively counting the occurrences of zero crossings with two counters and comparing the counted values, and the motor is delayed an electrical angle of 30°, by which a precise commutating time is obtained. The driving method provides a mask-based phase shift digital detection mechanism for effectively detecting true zero-crossing points. The driving method further provides an inhabitation mechanism with the function of soft-switch for inhibiting noise caused by transistor switching. By using these two counters, the time for the motor to rotate two electrical angles 30°−Δθ and 30°+Δθ are obtained and stored in two registers. The time period before and after the commutating point is added into a pulse width modulation (PWM) signal to reduce the noise and vibration.
