摘要： The present invention provides a high precision, low cost laser power calibration system. First, the photo signals output from a standard photo diode are received by a photo calibration system; then a set of standards consisting of the corresponding current signals and the power signals are saved in an EEPROM. Finally, the photo diode to be calibrated can be calibrated using the present system in accordance with the calibration standards.

摘要： A three-dimensional laser beam detection device. The three-dimensional laser beam detection device has a portion fixed to a laser source such as an optical head, an adjusting device provided on the fixed portion, and a laser beam detection portion coupled to the adjusting device. The adjusting device has a first table movably coupled to the fixed portion in a first direction, and a first adjusting portion coupled to the first table for moving the first table relatively to the fixed portion in the first direction. The first adjusting portion is formed within the adjusting device. The laser beam detection portion has a detector to detect the laser beam radiating from the laser source. The fixed portion has a fixed relative position to the laser source, and the detector is adjustable in relation to the laser source by performing adjustment with the adjusting device.

摘要： The present invention discloses a method for adjusting a tilt angle of an optical disc driver. The method includes the following steps. First, to move the optical pick up to close the outer end of the first and second guiding shafts. Next, the turntable drives a disc to rotate. Then, the light source provides a light to penetrate through the disc and the lens. The image sensor receives the reflection light from the disc and the lens. The monitor displays the traces projected from the reflection lights. According to the traces, the driving device adjusts the positions of the first and second guiding shafts.
