Abstract: A healthcare apparatus according to an embodiment includes: a plurality of light sources configured to emit light of different wavelengths onto an object; a light detector configured to measure an optical signal of each of the wavelengths by receiving light reflected or scattered from the object; and a processor configured to obtain a blood glucose level and a blood flow index by using the optical signal of each of the wavelengths, and to estimate at least one from among dietary information and dietary metabolism state information by monitoring a blood glucose level change and a blood flow index change after ingestion of a food.

Abstract: Provided is a spectrum measurement apparatus including a light source configured to emit light to a sample; a light detector configured to receive light, which is reflected or scattered from, or transmitted through the sample, and to measure an intensity of the received light, and a processor configured to reconstruct a spectrum of the sample for calibration while adjusting a value of a spectrum reconstruction parameter in response to the light detector receiving the light and measuring the intensity of the received light, and to determine an optimal value of the spectrum reconstruction parameter based on a similarity between the reconstructed spectrum of the sample for calibration and an original spectrum of the sample for calibration.
