| Abstract: | A smart method for generating focus servo signal is developed. In this method, the necessary astigmatism is generated by oblique parallel glass plate. The element has another action in this system; it can turn the light path to reduce the height of optical system. This method can simplify the structure of optical system for optical storage. The feasibility of this method is confirmed by ray tracing method. The experimental equipment is developed according this method. The performance of this scheme is proved by experimental result. |
