Realization of electronic circuits that can function like the visual faculty of living beings is required for the exploitation of intelligence-machines. This demand is responded in the present paper by proposing a fundamental electronic model of retina making use of both temporal and spatial frequency characteristics of vision. The model is constituted so as to manifest the characteristics of adaptation and contrast effects. The method of circuit design for the case of given specific characteristics is stated.

The Simultaneous Improvement of Output Energy Distribution and Gain of a Single Channel Electron Multiplier

Nobuyoshi Koshida, Seiji Suzuki, Makoto Kunii, Shigetomo Yoshida

1981 Volume 35 Issue 9 Pages 752-755

A new method is presented by which the unfavorable energy spread of output electrons from a single channel electron multiplier (CEM) is reduced with no reduction in gain. A modified output electrode and a thin film deposited within the channel produce a pronounced effect on the energy distribution and the gain, respectively. The full width ΔEat half-maximum of the energy distribution is decreased by one order of magnitude compared with a normal channel. The ΔEis also found to show nearly complete independence of operating conditions of the CEM. This method is potentially useful for application in image devices.
