Abstract
A non-invasive blood analyzer includes a light application device for applying light to a detection region of vessels contained in part of the living body, an imaging device for imaging the detection region to which light is applied, a fixing device for relatively fixing the imaging device and the part of the living body; a stabilizing device for stabilizing a focus of the imaging device with respect to the detection region; and an analyzer for analyzing the morphology and/or number of blood cells contained in the detection region by processing images captured with the imaging device, the light application device and the imaging device forming one image with a light application and capturing process during an interval of one ten thousandth to one billionth of a second.
