Abstract

Studies on the sensitivity of dichromated gelatin ( DCG) to blue and red light are reported. DCG sensitivity is improved when gelatin bias hardening is applied through the use of hardeners. Electron donors are found to increase the DCG light sensitivity. For hologram recording with a He-Ne laser, methylene green dye sensitizer is added and the role of dye concentration and pH of the solution is investigated.
