We calculate the signals of rod bipolar cells under pulsed illumination of the receptive field in the range of 0.02–10 photons per receptor. The calculations are performed based on a model considering the negative feedback of the first synapse with

This paper gives estimates of the SNR for a one-photon signal and the continuous noise of photoreceptor rods. It shows that negative feedback mediated via the horizontal cell needs to be taken into account when the reaction of the retina of the eye t

Based on a proposed model of the operation of the retina of a dark-adapted eye, the absolute sensitivity of the eye is calculated and is compared with that of a camera based on a cooled electron-multiplying CCD array. It is shown that the lowest obse

The study included 18 patients with recurrent strictures of the anterior urethra. In 16 patients the recurrence arose after several endoscopic operations for inflammatory urethral strictures, in 2--after plastic repair of the stricture by loganson an

The problem of creating a narrow-band filter that operates with wide-aperture (about 30°) light beams is solved in this paper. It describes the search for and the experimental certification of methods of creating a single-mode lightguide with a Brag

This paper shows that there currently are difficulties with the traditional interpretation of psychophysical experiments for determining the energy threshold of light perception. The functioning of the retina in the threshold regime is analyzed using

Based on an analysis of the dark-adaptation regime of the eye, a setup is developed and tested for calculating the illuminances corresponding to the image-perception threshold by an observer equipped with “electronic-vision” devices.

It is shown to be theoretically possible to use three-level molecular systems as a basis for creating arrays of uncooled bolometric detectors that convert a thermal image into a visible image and possess sensitivity as good as that of semiconductor b

The fluorescence-intensity variations on the surface of a photoisomerizing film of an organic dye under the action of the temperature contrasts that appear when a thermal image is projected onto it are considered. It is shown that a sensitive (δT=0.
