摘要： A projection apparatus includes an illuminating unit, an imaging unit, a lens unit, and a control unit. The illuminating unit includes a light source, and a light source driving module operable to drive the light source to provide an illumination beam. The imaging unit is operable so as to modulate the illumination beam into an image beam. The lens unit is disposed on an optical path of the image beam for projecting the image beam. The control unit is coupled electrically to the illuminating unit and the imaging unit. The control unit is configured to execute an activating thread for initializing the imaging unit after controlling initial driving of the light source by the light source driving module, and a monitoring thread for monitoring the light source driving module for a success signal that indicates successful provision of the illumination beam by the light source.

摘要： A laser scanning device and a control method thereof are provided. The method includes: providing a control signal to an oscillating reflective mirror of the device; setting a frequency of the control signal gradually decreased from a maximal-setting-value of a resonant frequency of the mirror; judging whether a light detector receives a laser light reflected by the mirror according to an edge signal of the detector; judging whether a pulse width of the edge signal is equal to a predetermined pulse width when the detector receives the laser light: (1) increasing the frequency of the control signal when the pulse width of the edge signal is greater than the predetermined pulse width, (2) decreasing the frequency of the control signal when the pulse width of the edge signal is less than the predetermined pulse width. The time and labor for measuring the scanning frequency of the mirror may be saved.
