An important step in constructing flexible fibre endoscopes is elaboration of methods for measuring their Optical and phototechnical characteristics. Methods and patterns of setups for measuring the field of vision angle, the field of fixation angle, resolving power, transmission coefficient and other parameters of flexible endoscopes are proposed. The knowledge of such parameters enables the key characteristics of endoscopes to be calculated, viz. the Optimal efficiency, informative capacity, information density per unit area of the fibrous band utilized in the device, etc.
