Paper Abstract

We propose the use of a nonlinear bacteriorhodopsin film to self-induce a Zernike-type filter in robust optical phase-contrast systems. The device requires relatively low light intensity levels (as low as 200 nW/cm2) at wavelengths around 633 nm and can contrast dynamical phase distributions.
