Mathematical and Computer Simulation of Visual Acuity in Imaging Devices

Alla V. Shymanska

Abstract—Image converters and intensifiers give access to a larger spectral domain of electromagnetic radiation than the human eye. They amplify low light images and increase the eye sensitivity. The visual acuity, and therefore, the range of vision of any image detector, is limited by optical properties of the detector, such as a modulation-transfer-function (MTF) and the value of noise, produced by the device. This paper presents the methods and computational algorithms for calculating MTF and the noise factor of image converters and intensifiers which incorporate an inverting electron optical system and a microchannel plate as an amplifier. The approach, presented here, enables one to improve the visual acuity of the device.

Index Terms—Image device, modulation-transfer-function, noise factor, visual acuity.
