Embodiment Construction

[0035] figure 1 It is a schematic diagram of the use state of the blood vessel imaging system according to an embodiment of the present invention. The blood vessel imaging system 100 of this embodiment includes a surface light source 110 , a viewing angle limiting sheet 120 and a near-infrared light sensor 130 . The surface light source 110 provides light with a divergence angle A12 less than or equal to 120 degrees. The viewing angle A14 of the viewing angle limiting sheet 120 is less than or equal to 60 degrees. The viewing angle limiting sheet 120 is stacked between the surface light source 110 and the near-infrared light sensor 130 .

[0036] The surface light source 110 provides light with a divergence angle A12 less than or equal to 120 degrees, which means that the angle between the light rays leaving any light-emitting point on the surface light source 110 and the normal direction of the surface light source 110 will be less than or equal to 60 degrees, so the total ...

Abstract

A blood vessel imaging system comprises an area light source, a visual angle limiting piece and a near-infrared light sensor. The area light source provides light with the divergence angle smaller than or equal to 120 degrees. The visual angle of the visual angle limiting piece is smaller than or equal to 60 degrees. The visual angle limiting sheet is stacked between the surface light source and the near-infrared light sensor. Or the near-infrared light sensor is stacked between the surface light source and the visual angle limiting sheet.

Description

technical field [0001] The present invention relates to an imaging system, and in particular to a blood vessel imaging system. Background technique [0002] As far as the prior art is concerned, the vascular imaging system on the market uses an infrared light source and a camera to photograph human tissue. Because the hemoglobin in blood vessels absorbs infrared light, a dark image of blood vessel outlines is obtained. In order to maintain the accuracy of vein identification, the shooting area should not be too small. However, the traditional vascular imaging system uses a lens to focus light, resulting in a limited viewing angle when shooting. If a large area is to be shot, a longer shooting distance is required, or partitioned. Multiple shots. Contents of the invention [0003] The invention provides a blood vessel imaging system, which can solve the problems encountered in large-area shooting. [0004] The blood vessel imaging system of the present invention includes...
