PORTABLE PUPIL DETECTION DEVICE WITH MULTIBAND STIMULATING LIGHT AND INFRARED ILLUMINATION
First Claim
1. A portable pupil detection device with multiband stimulating light and infrared illumination, which comprises at least one pupil detection module for detecting variation of a pupil of a testee, wherein each said pupil detection module includesan illuminating light source emitting invisible light beams;
- at least a stimulating light source emitting visible light beams;
at least one beamsplitter corresponding to said illuminating light source, said stimulating light source and an eye of said testee, cooperating with said illuminating light source and said eye to form a first optical path, and cooperating with said stimulating light source and said eye to form a second optical path;
a lens corresponding to said beamsplitter and receiving invisible light beams sent out by said beamsplitter to form an image of said eye;
an imaging element receiving said image of said eye from said lens; and
a control circuit controlling operations of said stimulating light source, said illuminating light source and said imaging element.
