Abstract:
1. A method to determine an optimal power level to encode information holographically, comprising the steps of: supplying a holographic data storage system comprising a light source, an evaluation image, a spatial light modulator, an optical detector, and a holographic data storage medium; setting (N) power levels, wherein (N) is greater than 1; selecting an (i)th power level, wherein (i) is initially set to 1, and wherein (i) is greater than or equal to 1 and less than or equal to (N); displaying said evaluation image on said spatial light modulator; energizing said light source using the (i)th power level; forming an (i)th hologram; encoding said (i)th hologram in said holographic data storage medium; determining if (i) equals (N); operative if (i) does not equal (N): incrementing (i) by unity; repeating said generating steps, said energizing step, said forming steps, said encoding step, said determining step, and optionally said incrementing step and said repeating step.
