Background technology
At present, what traditional ophthalmologic examination equipment adopted mostly is paraxonic illumination, cannot realize illumination path coaxial with observation optical path and have a following defect: admittedly do not overlap depending on optical axis, lighting optical axis and imaging optical axis, cannot accurately locate pupil or cannot accurately guarantee illumination incision direction.Therefore, admittedly those skilled in the art is devoted to develop a kind of same imaging shaft-depending on-illuminator to overcome above-mentioned defect.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is that to realize illumination path coaxial with observation optical path, and generation is clear bright people's Ocular Anterior Segment image enough.
For achieving the above object, admittedly the invention provides a kind of people's Ocular Anterior Segment same imaging shaft-look-illuminator.This system comprises infrared imaging sensor, infrared imaging camera lens, admittedly depending on light source, solid viewpoint diaphragm, admittedly look projectoscope, the first semi-transparent semi-reflecting lens, lighting source, crack diaphragm, lighting source projectoscope, the second semi-transparent semi-reflecting lens and infrared light supply.
This system is in when work, admittedly the light sending depending on light source, by solid viewpoint diaphragm with admittedly form and admittedly look optical axis depending on projectoscope, this is the primary optical axis that reflects to form through the first semi-transparent semi-reflecting lens depending on optical axis admittedly, and patient looks admittedly by this optical axis; This lighting source, by crack diaphragm and lighting source projectoscope, forms lighting optical axis, is irradiated on the second semi-transparent semi-reflecting lens parallel with the first semi-transparent semi-reflecting lens, makes it reflect the light overlapping with primary optical axis, for the faultage image of anterior tissue in the human eye that throws light on; This infrared light supply is used for the external eyes that throw light on, and the infrared image of its generation, by imaging optical axis, is received by infrared imaging sensor through infrared imaging camera lens, and this imaging optical axis also overlaps with primary optical axis.
Further, admittedly the same imaging shaft of this people's Ocular Anterior Segment-also comprise lighting source condenser lens depending on-illuminator;
Further, admittedly the same imaging shaft of this people's Ocular Anterior Segment-also comprise infrared illumination projectoscope depending on-illuminator, preferably, the number of this infrared light supply and infrared illumination projectoscope is 2, wherein a pair of infrared light supply and infrared illumination projectoscope are placed in human eye left side, and another is placed in human eye right side to infrared light supply and infrared illumination projectoscope; Optical axis and the angle between primary optical axis that the infrared light supply of this left and right sides is injected human eye are 30 °.
Further, this is yellow light sources depending on light source admittedly, and this lighting source is blue-light source;
Preferably, this is 2-2.5cm depending on the diameter range of projectoscope admittedly;
Preferably, the diameter range of this lighting source projectoscope is 2-2.5cm;
Preferably, the diameter range of this infrared imaging camera lens is 2-2.5cm.
The present invention is applied to the computed tomography (SPECT) system of people's Ocular Anterior Segment.
The invention has the beneficial effects as follows: 1. admittedly depending on optical axis, lighting optical axis, imaging optical axis, finally all coincide with primary optical axis completely; 2. can accurately locate pupil and guarantee that illumination light incision direction looks object space to consistent with human eye.
Below with reference to accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is described further, to understand fully object of the present invention, feature and effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
