STEREOSCOPIC SCREEN CONSTITUTION, ADJUSTMENT METHOD AND APPARATUS THEREFOR

摘要

PPROBLEM TO BE SOLVED: To provide a stereoscopic screen constitution with which a large scale reduction in the size of an optical system especially mainly of an objective reflection mirror is realized, an adjustment method and an apparatus therefor. PSOLUTION: On the basis of the rotation of a screen by vertical refraction of an optical axis, the refractive angle of the optical axis is adjusted and set so that conversely the amounts of rotation for the right and left pictures are made equal, thus a longitudinal stereoscopic screen having a shape in which the entire picture is rotated and having simple structure is realized. Moreover, field angle adjustment is conducted in a simple manner by newly introducing display marks which are set and separated by a distance equivalent to the vertical field angle difference, on the monitor screen of the longitudinal stereoscopic screen.
