Abstract

For commercialization of holographic storage drives, the effects of temperature changes on holographic medium is critical. There has been no systematic study on the effect of temperature change on hologram recording properties. We believe that the monomer-diffusion speed and polymerization rate changes are critical for hologram-recording properties and estimate those parameters on each temperature using the photopolymer medium process simulation we have developed. We describe how these parameters affect actual recording properties such as sensitivity, M=# and so on. Moreover, we propose a method for compensating temperature changes, and confirm the success of this.
