“…Based on studies [8] and analysis of other works [9][10][11][12][13][14][15] of the movements of optoelectronic converters at small and large ranges made of hollow light guides, the following conclusions were obtained: with small limits of movement, maximum sensitivity is achieved at minimum values of the diameter of the hollow light guide, and with large limits of movement, respectively, at maximum values of the diameter of the hollow light guide. Their design features are also discussed here [8,16,17,18]. On the basis of ( 1) and ( 2), the distribution of the relative value F(x)/F0 is constructed with some average value of the reflection coefficient, for example, ρ = 0.5, for several possible diameters of the hollow light guide.…”
