The Measure Of The Light Scattered From The Information Pit Of The Disk In Waveguide Multiplayer Optical Storage

Waveguide multiplayer optical memory is a kind of new 3D optical memory based on new principle. It can read the data by utilizing the effect of scattering light of waveguide defect. In the experiment, we use PMT to detect the scattering light, so how to process and collect the output of the PMT is a key technique which must be dealt with. In the experiment, we establish a set of experiment equipment to measure and collect the output of PMT. This paper introduces this experiment equipment and the analysis of the data collected. The elementary experiment result indicates that this system can realize processing and collection of the. output of PMT and we can distinguish and measure the change of the signal while there is a information pit or not.
