New kind of optical system for vein detector system

To detect the biological reaction on the vein is an important part of the biological technique. In this paper, we present a description of our work in recent years on imaging in vein detector system. Novel routes to achieving alternative high sensitive detector ability are presented. The classifications and characteristics of the detector system are outlined firstly. Then, some optical design results are presented and compared in detail. At last, the optimization and the future possible research works are explored. The optics part of the detection system is generally analyzed. The first system presented considers a LED light source type arrangement where a detailed investigation of different light source is performed. The effect of varying these parameters on the optical sectioning characteristics and on the light throughput is evaluated. We also discuss current trends in vein detector system.
