MEASUREMENT DEVICE AND MEASUREMENT METHOD

摘要

A measurement device includes a light sensing element on which light from a measurement target region placing a measurement target thereon forms an image, and a plurality of light emitting elements that are disposed around the light sensing element and radiate light to the measurement target region, wherein the plurality of light emitting elements are disposed to be tilted with respect to the normal line of the measurement target region such that the central line of radiated emission from each of the light emitting elements passes through a substantial center of the measurement target region.
