An Experimental Holographic Media Storage System Uses A Flexible Photopolymer Disk During Rotation The Disk Tilts Mak 1 (175.32 KiB) Viewed 30 times

An experimental holographic media storage system uses a flexible photopolymer disk. During rotation, the disk tilts, making information retrieval difficult. A system that compensates for the tilt has been developed. For this, a laser beam is focused on the disk surface and disk variations are measured through reflection. A mirror is in turn adjusted to align with the disk and makes information retrieval possible. A video camera provides the sight for the robot and the tracking loop. Assuming the system transfer function is given by G(s) = 25 (s+1) s(s+2)(s² +2s+16) 1. Use frequency response techniques to determine the following: Gain Margin Phase Margin Zero dB Frequency 180° Frequency 2. Does the system stable? Explain. ●
