Problems solved by technology

Because the existing visual stimulator is a single display with a fixed position, the display cannot be moved during the test, nor can the direction and angle be adjusted, thus bringing a large amount of errors to the experiment. Specifically, there are the following inconveniences: 1. 1. The distance between the subject and the display cannot be accurately measured; 2. When conducting polarity experiments, it is easy to cause errors in the measurement of the angle of view of the animal; 3. When conducting different experiments, once the position of the subject or the content of the experiment changes, The display screen cannot adjust the direction and angle well, which brings a lot of errors to the experiment; 4. It is impossible to accurately locate the position of the subject

Abstract

The invention discloses a visual stimulator capable of self-adaption precise positioning. The visual stimulator comprises a display which is embedded in a display support; the display support is movably connected with a position adjustment support through a connection rod; a telescopic shaft is hinged to the display support above the display; and the end part of the telescopic shaft is provided with a laser emitter. The visual stimulator has the advantages that the structure is simple; manufacturing cost is low; adjustment is convenient during use; the display embedded in the display support can move vertically and horizontally according to testing conditions, so that precision of various tests is ensured; and besides, the telescopic shaft hinged to the display support can rotate for 360 degrees, and the position of a testee can be precisely positioned through the laser emitter arranged on the end part of the telescopic shaft.

Description

Technical field [0001] The invention relates to an apparatus for biological vision training, in particular to a visual stimulator with adaptive and precise positioning. Background technique [0002] After hundreds of millions of years of evolution in nature, organisms have formed a very superior visual information processing mechanism. Vision research is the science of exploring biological visual information processing mechanisms, studying the extraction of visual evoked potentials and the laws of brain function imaging, and the graphic stimulation system is an indispensable device in visual research. Therefore, the development of graphic stimulation systems is of great significance for cognizing biological visual systems, studying machine vision and visual rehabilitation engineering. [0003] The main experimental items of the visual stimulator are the rat receptive field characteristic experiment and the rat image restoration experiment. The purpose of the experiment is: 1. Meas...
