Spectacle optical filter design method with blood oxygen information enhancement function and spectacles

Abstract

The invention relates to a design method of a glasses optical filter with a blood oxygen information enhancement function and glasses. The method comprises the following steps: S1, constructing composite spectral efficiency information by combining actual illumination spectral information and spectral quantum efficiency information of three types of cone cells of human eyes; s2, setting ranges of optical characteristic parameters and physiological parameters of human tissues at specific parts, and constructing a high-dimensional parameter space; s3, generating a tissue model for each sampling point in the high-dimensional parameter space, and simulating propagation of each sampling wavelength photon in the tissue model to obtain a reflected light intensity image; s4, acquiring a reflected light intensity gray average data set based on each reflected light intensity image, and calculating to obtain a corresponding tissue blood oxygen real data set; s5, assuming the spectral response of the optical filter to be designed, and constructing an optimization model; and S6, solving to obtain an optimal value of the optical filter spectral response design. Compared with the prior art, the blood oxygen information can be enhanced and presented, and first aid and rescue of doctors can be more effectively assisted.

Description

technical field [0001] The invention relates to the fields of optical computing and medical optical imaging, in particular to a design method and glasses for glasses filters with blood oxygen information enhancement function. Background technique [0002] Tissue oxygen (SO 2 ) status is an important indicator of emergency medicine, and real-time acquisition of tissue blood oxygen information in the surgical area can provide important assistance for rescuing patients. Traditional biochemical tests are invasive and time-consuming; traditional optical PPG oximetry can only provide local and rough blood oxygen information. Non-contact blood oxygen measurement by optical imaging methods, such as iPPG, requires special lighting, camera recording, computer post-processing, and monitor display. In scenes with limited lighting, equipment, and power conditions such as the field or battlefield, the above conditions and equipment are often difficult to adapt to. From the perspective ...
