We investigate the potential of high-resolution and large space-bandwidth product holographic lensless imaging by using bacteriorhodopsin film as a real-time material under He-Ne laser illumination. The imaging ref lectivity is found to be linearly proportional to the reading light intensity when the hologram is under short laser pulse stimulation. The time response of the recording process is characterized by two exponentially increasing functions that are related to the intensity modulation of the illumination. An image resolution of 80 linesymm and a space-bandwidth product of [inline formula] are obtained.
