摘要： A laser optical touch control module includes a light emitting part with a laser light source and a light receiving part with a position sensor. A laser beam is emitted from the laser light source and reflected by a wide angle optical element. Thus a light fan of the reflected light is larger than 90 degrees to form a wide angle linear light beam. The position of a touch control widget is obtained by a sensor of the light receiving part that detects the linear light beam blocked and reflected by the touch control widget. An analog-to-digital conversion system includes a variable reference level generator that calculates to generate a variable reference level according to different variances. Then the sensor output data is converted into a digital signal based on the reference voltage level by a digital comparator and the digital signal is output to a processor.

摘要： An in-line laser scanning unit (LSU) with multiple light beams is disclosed. The LSU includes a minimized in-line mirror set composed by a plurality of vertically stacked Micro Electronic Mechanical System (MEMS) oscillatory mirrors and a linear corresponding scanning lens set formed by a plurality of F-Sin θ lens stacked vertically so as to correct the variation of reflective angle of the oscillatory mirror that is sinusoidal in time. Thus the scanning speed of multiple laser beams on the image plane is constant. Therefore, the volume of color printers is effectively reduced and the scanning efficiency is improved when the LSU in accordance with the present invention is applied to the optical engines of color printers.

The display device includes a laser source for emitting a laser beam, a pre-optics for processing the laser beam, a light scan member such as a MEMS mirror for converting the processed laser beam into a scanning light beam, and/or a corresponding post-optics.

摘要： A laser scanning unit mainly includes a semiconductor laser, a collimator, a micro electronic mechanic system (MEMS) oscillatory mirror, and an fθ lens or an fsin θ lens. The MEMS oscillatory mirror is disposed between the collimator and the fθ lens to replace a conventional rotary polygonal mirror for controlling a direction in which laser beams are projected from the oscillatory mirror to the fθ lens. With the MEMS oscillatory mirror, the cylindrical lens may be omitted from the laser scanning unit and noises produced by the polygonal mirror rotating at high speed may be avoided. Moreover, the MEMS oscillatory mirror allows bi-directional scanning to therefore enable increased scanning frequency, simplified structure, and improved scanning efficiency.
