Unattended visual quality detector and system

The invention provides an unattended visual quality detector and system. The visual quality detector comprises a display; the two fixed reflectors are used for enabling a light path between the eyepiece and a sighting mark on the display to be reflected at least once on each fixed reflector; at least one movable mirror which can be moved in or out of the optical path according to a detection purpose; therefore, light emitted by the sighting mark is reflected into the eyepiece through the movable reflective mirror. The unattended visual quality detector provided by the invention can simultaneously have near vision and far vision detection capabilities in a relatively small space, has low requirements on pixels of a display for displaying sighting marks, and can greatly save the cost. 本发明提供了一种无人值守的视觉质量检测仪以及系统，视觉质量检测仪包括：显示器；两个固定反光镜，用于使目镜与所述显示器上视标之间的光路在每个固定反光镜上发生至少一次反射；可根据检测目的移入或移出所述光路的至少一个可移动反光镜；以使所述视标发出的光线通过所述可移动反光镜反射入目镜中。本发明所提供的无人值守的视觉质量检测仪，可以在较小的空间同时具备近视力以及远视力的检测能力，且对于显示视标的显示器的像素要求不高，可以大大节约成本。
