Abstract	This work presents a measurement methodology that estimates the perceived visual quality of a multiview 3D display. It uses the notion of a display passband, which considers the display as a signal processing channel and describes which spatioangular frequencies can be visualised with an acceptable quality. The methodology starts by measuring the optical parameters of the display. Then, a set of test signals are visualised on the display and photographed from a range of observation directions. Each test image is a sinusoidal grating with three frequency components - horizontal, vertical and angular one. The spectrum of each photograph is calculated and the distortions introduced by the display are analysed in the frequency domain. A model of the contrast sensitivity function (CSF) is applied in order to estimate the visually predominant frequency. If the dominant frequency in the input remains dominant in the output, the input frequency is deemed as belonging to the display passband. In the last step, the shape and size of the derived passband is used to calculate the equivalent spatioangular resolution of the display.
