mosaikmire for measuring the number of pixels different contrast and color, the optical instrument and also for the estimation of the influence of the moire effects

摘要

mosaikmire of regularly arranged elementary cells (segments) of the different measure, characterised in that its cells by the appropriate concentric logarithmic spiral and / or polradien and / or circular arc and / or tendons of these curves are discussed in such a way that it is in the shape and surface area at regular polygon approach each other, and that their cells (high contrast in pairs, for example, such as checkerboard) are dyed.
