Description
Technical field
The present invention relates in medical scientific domain, the technology of testing result is realized by technological means, it is specially a kind of high
Drug addict's instrument for examining pupil of accurate verification and measurement ratio.
Background technique
The pupillary movements Fast Detection Technique of drug addict is mature at present, and common is exactly personnel's pupil of being involved in drug traffic
Detection device, principle are the pupillary movements process and eyeball by infrared light sources and infrared camera to testee
The modes such as the frequency of movement and blink are detected, and are recorded under half-light environment after the dynamic attribute of pupil, and light stimulus is opened, and
Pupillary movements in record 1 minute can determine whether tested personnel is drug addict to compare by record.
But the defect of the product is that promising result is not achieved in Detection accuracy at present, to find out its cause, being because to quilt
The detection precision of survey personnel's pupil goes wrong, and when being primarily due to tested, the glasses of tested personnel are wrapped in front of eyepiece,
To be carried out under pitch-dark dark surrounds, and due to needing human eye to be unable to complete focusing, the eyeball of tested personnel under dark surrounds
Can move left and right in the detection process, or what is moved up and down tamper, so that the information collection to pupil has an impact, even and if by
The eyeball of survey personnel is remain stationary, it is also possible to which its eyeball is in strabismus state, still can generate interference to testing result, cause to examine
Dendrometry loses or testing result is not accurate enough.
Summary of the invention
The purpose of the present invention is to provide one kind can be improved detection precision, and the pupil for improving tested personnel captures, is steady
Drug addict's instrument for examining pupil of the accurate verification and measurement ratio of the height of its fixed visual fixations process, specifically, the present invention is implemented as follows:
A kind of drug addict's instrument for examining pupil of high accurate verification and measurement ratio, including detection device shell, camera shooting lens barrel, stimulation mirror
Cylinder, the camera shooting lens barrel includes eyepiece, the camera that tail portion is installed, the control circuit connecting with camera, in the camera lens
Eyepiece rear is equipped with dim light light emitting device in cylinder, and the dim light light emitting device is connected to control circuit.
Further, the dim light light emitting device is light emission luminance size between 0.005-0.05cd/ square metres；Or
10-3-10-1Between LUX, the emission wavelength of light emitting device is at 495~570 nanometers.
Further, the light emitting device issues the faint light source of green, blue or yellow.
Further, the frequency of the green light source is between 526-606THz；The wavelength of the blue light source is in 476-
Between 495nm, frequency is between 606-630THz；The wavelength of the yellow light sources is between 570-590nm, frequency 580-
Between 562THz.
Further, the position of the dim light lamp group is located in the intermediate region at eyepiece rear and is fixedly mounted, or, described weak
Light lamp group is mounted on eyepiece rear in a manner of the variable installing and dismounting in position.
Further, the luminous shape of the dim light lamp group is dotted or with a certain shape or a certain pattern.
Further, the eyepiece outer rim is in the circular curve type to concave, and the two sides of described device shell are equipped with patch
Close the dactylostyle groove of finger.
The working principle of the invention and beneficial effect introduction: the mankind have the light of same intensity different wave length different quick
Sensitivity.Appreciable wave-length coverage 380nm~780nm, referred to as visible light.Maximum light wherein is generated to green (550nm) light
Strong susceptibility.By being equipped with dim light light emitting device at eyepiece rear, so that occurring in dark detection environment faint
Light, and the instinct of human eye be exactly can watch attentively it can be seen that thing, at this point, dim light light emitting device be in dark it is unique indistinctly
Visual object, therefore illuminator holding will be kept a close watch in the subconscious situation of human eye and watch a period of time attentively, so that eyeball be allowed to exist
It will not disorderly turn under dark surrounds, keep the steady state watched attentively instead, to ensure that pupil detection process is gone on smoothly；Together
When, faint light will not generate interference to the feature of pupil, and distinctive brightness, wavelength will not stimulate the feelings of testing staff
Thread makes it keep quite, gentle psychological condition, so that the acquisition to the pupil feature of tested personnel is improved, it is final to improve
The precision and reliability of detection.
