Paper Abstract

In recent years polymer films based on bacteriorhodopsin (BR) have attracted a lot of attention in the area of optical imaging systems. The high photosensitivity of these films allows the processing of low-power optical signals (several mW/cm2 CW gas laser irradiation). Spatial resolution does not fall below 5000 lines/mm, photoresponse time is 50 microsecond(s) and images can be recorded and erased over million cycles. Polymer film with BR combine a dynamic recording with optical image processing. The characteristics of anisotropically-saturating nonlinearity of polymer films with BR allow a suppression of the background with greater intensity than usable signal intensity of be performed. Low saturation intensity of the polymer films with BR allows the operation of the polarization of low-intensity signals to be realized. Nonlinear photoresponse of the high photosensitivity BR genetic variant Asp96-Glu is studied in this work too. We hope that the polymer films based on BR and its analogs will find potential use precisely in the medical low- light-level imaging systems.
