Demonstration of spatial light modulation by using reversible photochemical reaction of bacteriorhodopsin between ground state and K intermediate at room temperature

We have experimentally studied about spatial light modulation by using the early photochemical product of bacteriorhodopsin(bR) called K intermediate at room temperature. In general, it is necessary for using K intermediate to lower the temperature of bR under 77 K. In this paper, we propose a new technique to use K intermediate at room temperature. We demonstrated experimentally spatial light modulation by using K intermediate at room temperature.
