Description

Pupil detector sleeve bearing structure

Technical Field

The utility model relates to a pupil detector technical field specifically is a pupil detector sleeve bearing structure.

Background

The pupil is located in the anterior portion of the ocular vascular membrane, i.e., the center of the sclera and the round aperture. The smooth muscle, which is annularly arranged along the pupil, is called the sphincter pupillae. Contraction of the sphincter muscle constricts the pupil. The smooth muscles radially arranged along the pupil are called the mydriasis muscle. The mydriasis is enlarged when the magnifying muscles contract. The pupil can be enlarged or reduced, so that the light quantity entering the eyeball can be adjusted. The normal human pupil can reflexively adjust its own size. When the light is enhanced, the pupil is contracted; when light is weakened, pupils are enlarged, the technology for rapidly detecting the dynamic change of the pupils of drug addicts is mature at present, and the pupil detection device for the drug addicts is common, and the principle of the device is to detect the dynamic change process of the pupils of a tested person, eyeball movement, blinking frequency and other modes through an infrared light source and an infrared camera, record the dynamic property of the pupils in a dark light environment, start light stimulation, record the dynamic change of the pupils within 1 minute, and judge whether the tested person is the drug addict or not through record comparison.
