Abstract
DVD pick-up head is the backbone in our research. We remove the focusing Lens from the DVD pick-up head to collimate light. When the reflection of the object produce make a angle, there are signals got from photo detect. After the processing of DSP, the angle could be computed and displayed using LCD. A two dimension electronic level could be designed according to the variations of angle measure by DVD pick-up head. Straightness of the two axis of the moving object could be measured if knife edge is combined. The other major point of our experiment is that microchip is used to calculate and process in our system without using computer.
