摘要：
The invention relates to a miniaturised instrument for simulating simultaneous vision by generating masks with a single image-forming optical channel. The instrument comprises: a mask-generating element (EGM) which generates at least two complementary masks, with a temporal frequency of alternation, such that when one partially blocks the incident light, the other allows the incident light to partially pass, and vice versa； an adjustable lens (LA) of variable optical power, which generates, with said frequency of alternation, at least two different optical powers corresponding to at least two observation distances. The EGM and the LA are located in a single optical channel via which the incident light circulates, such that each mask of the EGM is temporally synchronised with a power of the LA. The combination of all the masks and optical powers produces a pupil pattern, via high-speed temporal fusion, in which pattern at least two optical powers corresponding to at least two observation distances are combined.
