Title: MEASURING INSTRUMENT
Abstract:
The measuring instrument is provided with: a light-emitting means (201) for irradiating light; a first light-receiving means (211) and a second light-receiving means (212) for receiving irradiated light returning from the object that is being measured (500); and a calculation means (320) for calculating information relating to the object that is being measured on the basis of the difference between the sum signal and the difference signal of the light received by the first light-receiving means and the light received by the second light-receiving means. Such a measuring instrument makes it possible to remove unnecessary components such as body movements and accurately measure information on the object that is being measured.
