摘要

The device has two identical plane objects, where each plane object is arranged in an independent darkroom. An alternative indicator light assembly illuminates the plane objects directly or indirectly. The plane object is visualized through an optical system in a rapid alternate manner to utilize effects of retinal remanence by an eye, where distance i.e. interpupillary distance, between two eyepieces (1) is adjusted along horizontal direction (3) and fixed by a screw. Lenses (2) positioned and fixed in the eyepieces are formed in two screwable parts.
