We propose a new technique for an interconversion between a three dimensional (3-D) spatial signal and a temporal signal. It is realized by combination of a holographic technique, a 2-D spatial filtering technique and a time-space conversion techniqu

Summary 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 tempe
