Abstract: ABSTRACT NON-INVASIVE OPTICAL APPARATUS AND METHOD FOR DETERMINING HEMOGLOBIN AND GLYCATED HEMOGLOBIN FROM CONJUNCTIVAL IMAGES The present invention relates to a non-invasive optical measurement apparatus (100) and a method (200) for determining Hemoglobin (Hb) and Glycated Hemoglobin (HbA1c) from an image of a lower-eyelid conjunctival region. The apparatus (100) comprises an image sensor (102), illumination assembly (104), positioning structure (106), and processor (108) configured to generate a processed conjunctival-region representation and supply the same to first and second processing paths. The first processing path uses colour feature vectors, K-Means clustering and statistical colour characteristics to calculate Hb, while the second processing path uses a convolutional neural network to generate image feature maps and calculate HbA1c. The method (200) comprises acquiring (202), illuminating (204), generating (206), and supplying (208) the processed representation, including image preprocessing, colour processing, image-quality assessment and temporal image comparison. FIG. 1 will be the reference figure.
