Problems solved by technology

This method has a slight improvement in accuracy compared to the dual-wavelength method, but the improvement is not particularly ideal due to too much noise in the skin
At the same time, the complexity of the measurement method increases the cost and the complexity of data processing, whic

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] see figure 1 , the embodiment of the present invention provides an optical path device, which includes an illumination optical path and an imaging optical path, and the functions of each component will be described in detail below.

[0020] The light source 01 to the sclera 06 constitutes the illumination light path of the device, and the light source 01 uses a xenon lamp to meet the illumination requirements of 430nm, 514nm, and 550nm.

[0021] In order to make the illumination brightness higher and the uniformity better, a condenser lens 02 is placed in front of the light source 01, and i...

Abstract

The invention provides a device and a method for detecting bilirubin for sclera imaging. A collecting lens, a diaphragm, a first optical lens and a transflective lens are placed from a lighting lightsource to a sclera in sequence; light is deflected by 90 degrees after passing through the transflective lens; and in the direction, a second optical lens, a trapezoidal prism, a third optical lens, aCCD and an external data processor are placed outwards from the transflective lens in sequence. According to the method, the thickness of the sclera is determined by measuring the brightness values of different points on the sclera, and the concentration numerical value of the bilirubin is determined by solving equations through the imaging brightness ratio under three wavelengths.

Description

technical field [0001] The invention relates to a bilirubin detection device and method for sclera imaging, which belongs to the field of optical detection, and more specifically detects the optical scattering properties of human eyes. Background technique [0002] At present, the detection of bilirubin is mainly divided into invasive detection and non-invasive detection. The invasive test is the serum test method. The collected blood is centrifuged in a centrifuge, the supernatant is separated, and then determined by chemical methods. Invasive testing has high accuracy, but it will cause wounds and pain, the testing time is long, and it is difficult for newborns to collect blood. [0003] Non-invasive detection is mainly percutaneous optical detection method. Among them, the dual-wavelength method considers the spectral characteristics of hemoglobin and bilirubin, selects 460nm and 550nm spectral analysis, removes the influence of hemoglobin on the detection of bilirubin,...
