Abstract: A laser collimator module installed on a mobile device for a camera program installed in the mobile device to operate photo-taking. A microprocessor on the mobile device activates a camera unit to record an image with an image data. The image data includes a plurality of pixel values for further retrieving of a set of pixel values horizontally and a pixel value of a dot within the set of pixel values. When the microprocessor matches the set of pixel values with a horizontal distance in the image, the microprocessor renders a point of collimated light projected by the laser collimator module as a reference point for further measurement.

Abstract: A laser diode module with a built-in high-frequency modulation IC used to remove the reflected noise generated as the laser beam reads the signal to be played back and directly packaged within a metal cap. The high-frequency modulation IC creates an electrical connection through wire bonding with several connection legs and the laser diode module. The packaged laser diode module has four connection legs. Two of these connection legs act as a positive and a negative terminal for supplying power to the built-in high-frequency modulation IC. The other two connection legs are electrically connected to an external automatic power control (APC) circuit and act as the positive terminal of the laser diode and the photo diode, respectively. In this way, the inconvenience of externally attaching a high-frequency current producing circuit board can be avoided, the productivity can be enhanced and the radiation of electromagnetic interference (EMI) can be reduced.
