The optical system used in this method includes

The optical system used in this method includes pLA0a

Based on tissue absorption of infrared light. When the infrared light shines through the hand the tissues will absorb the infrared light, the blood vessel containing the hemoglobin will absorb more than the other areas in the resulting image will show up as a dark area while the surrounding skin absorbs the light. Lower absorption will show up in the resulting image as a bright area. The image will be captured through the optical system and camera and then displayed on the computer. The near-infrared light sources used include high-power LEDs (light emitting diodes) with wavelengths of 740 nm, 850 nm, and 940 nm. The system uses a combined method of capturing scattered and transmitted light at the same time. In this method, the camera is placed in front of the subject to determine the hand tendon, and the infrared illuminator LEDs will be placed on the front and back of the subject to determine the hand tendon.
