Abstract: An apparatus is provided. The apparatus includes a memory, a second type spectrum measurer, and a processor. The memory stores an individualized blood sugar estimation model. The second type spectrum measurer measures second type spectrum data for a skin of a user. The processor calculates blood sugar of the user based on the measured second type spectrum data and the individualized blood sugar model. The blood sugar model is generated based on blood sugar profile data of the user calculated based on a first type spectrum-blood sugar profile relationship model and training second type spectrum data for the skin of the user.

Abstract: An optical measuring device including a light source, a light beam path adjuster, a light detector and a controller is provided. The light source may emit light toward an object in a predetermined progress direction. The light beam path adjuster may be disposed between the light source and the object and may change a progress path of the light emitted from the light source. The light detector may receive the light that is reflected from the object after passing through the light beam path adjuster. The controller may compare a first effective beam path length of the reflected light that the light detector receives with a predetermined target beam path length and control a refractive angle of the light beam path adjuster based on a beam path length difference between the first effective beam path length and the predetermined target beam path length.
