  • Patent number: 5791345
    Abstract: A non-invasive blood analyzer is intended to capture images of a prescribed volume of blood in a blood vessel in a non-invasive manner and with a good contrast without collecting blood from a living body. The non-invasive blood analyzer includes a light application device for illuminating a detection region of vessels contained in a part of a living body, an image capturing device for capturing images of the detection region illuminated by the light application device, and an analyzer for analyzing blood components contained in the detection region by processing the images captured by the image capturing device. The image capturing device includes an object lens for converging the reflected light from the detection region. The light application device illuminates the detection region at an incident angle larger than an aperture angle of the object lens with respect to the detection region to provide dark-field illumination.
