Claim Text:
1. An optical measurement apparatus comprising: one or more light irradiators, each of which irradiates light with a wavelength of 200 nm to 1500 nm onto a living object at an incident light position on a surface of the living object, respectively; one or more luminescent cells, each of which is filled with a luminescent material and has a first surface which is disposed directly on the surface of the living object at a light detection position spaced apart from the incident light position on the surface of the living object, respectively; an optical detector which detects light emitted from the luminescent material; and a shield member which covers at least another surface of each of the one or more luminescent cells other than the first surface that is in contact with the surface of the living object, respectively, and which shields the luminescent material from stray light having the wavelength of the light from the one or more light irradiators, respectively, and a part of the shield member of each of the one or more luminescent cells transmits light emitted from the luminescent material, wherein the optical detector is disposed on the same side of the living object as the one or more light irradiators with respect to the surface of the living object on which each of the one or more luminescent cells is disposed, and wherein the optical detector measures a luminescence intensity of the light emitted from the luminescent material of each of the one or more luminescent cells, respectively, while the light is irradiated by the one or more light irradiators, respectively, and absorption information of the incident light in the living object is measured from the luminescence intensity measured by the optical detector.
