Abstract: |
The reading out signal inspection method for blue light multi step storage device with the channel distance less than 0.52millimter works with recovering the clock signal from the reading out signal(rt) from the blue light multi step photomemory, sampling (rt) based on the clock signal to get the sequence (rk), getting target signal sequence (zk) before filtering the (rk), inputting (rk) to each survived path to get their path measurement, screening for the shortest path measurement as the final path output. It also provides a reading out signal inspection. |
