We propose the use of a nonlinear bacterior- hodopsin film to self-induce a Zernike-type filter in robust optical phase-contrast systems. The device requires rela- tively low light intensity levels (as low as 200 nW/cm 2 )a t wavelengths around 633 nm and can contrast dynamical phase distributions.
