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.
