Near-IR rays are used to be able to measure calorie, thereby measuring the calorie of an object easily and in a short time by a non-destructive method. A calorie measuring device comprising an object holding unit (1) having a table (2) on which to mount an object (M) to be examined, a light source unit (20) irradiating the object (M) on the table (2) with a near-IR-region ray, a light reception unit (30) receiving a reflection light or transmitted light from the object (M), and a control unit (40) calculating the calorie of the object (M) based on the absorbance of light received by the reception unit (30), wherein the control unit (40) computes the calorie of the object (M) from a regression expression calculated by a quadratic differential spectrum multiple regression analysis at the absorbance of a near-IR ray applied in advance to and reflected off or passed through a calorie-known sample object (M) and from the absorbance of light received by the reception unit (30).

Les rayons proches de l~infrarouge sont utilisés pour leur pouvoir de mesure de calorie, mesurant ainsi facilement et rapidement les calories d~un objet par une méthode non-destructrice. Un dispositif de mesure de calorie comprenant une unité (1) pour maintenir l~objet, ayant une table (2) sur laquelle monter l~objet (M) à examiner, une unité de source de lumière (20) irradiant l~objet (M) sur la table (2) d~un rayon proche de l~infrarouge, une unité de réception de la lumière (30) recevant une lumière transmise ou réfléchie par l~objet (M), et une unité de contrôle (40) calculant les calories de l~objet en s~appuyant sur l~absorbance de la lumière reçue par l~unité de réception (30), où l~unité de contrôle calcule les calories de l~objet (M) à partir d~une expression de régression calculée par une analyse du spectre quadratique différentiel à régression multiple, de l~absorbance d~un rayon lumineux proche de l~infrarouge appliqué par avance et réfléchi ou passant à travers un objet échantillon (M) de calorie connue et à partir de l~absorbance de lumière reçue par l~unité de réception (30).
