Abstract: A spectrophotometer is provided, which comprises a receiving part diffusing an incident light, a first broadband filter group, and a detector detecting the light having passed through the first broadband filter group, in order to easily select and detect a plurality of lights having specific wavelengths, wherein the first broadband filter group comprises a first broadband filter arranged to have a first angle with respect to an incident direction of light to enable the incident light to pass through a first wavelength band, a second broadband filter arranged to have a second angle, which is different from the first angle, with respect to an incident direction of light to enable the light having passed through the first broadband filter to pass through a second wavelength band, and a first path compensation means for adjusting a path of the light having passed through the second broadband filter to be identical to a path of the light having passed through the first broadband filter, wherein the first broadband filter, the second broadband filter and the first path compensation means are arranged in series with respect to the incident direction of light. Accordingly, it is possible to increase the efficiency of the outputted light compared to the incident light, and to detect a plurality of lights having the desired specific wavelengths at the same time.

Abstract: Correction of a non-invasive blood glucose measurement measured from a video image. Correction includes irradiating white light on the skin, filtering the white light reflected from the skin by a first wavelength filter and a second wavelength filter, obtaining a first signal including a blood glucose signal and a pulse signal based on a video image generated by the white light filtered by the first wavelength filter, obtaining a second signal including a pulse signal based on a video image generated by the white light filtered by the second wavelength filter, obtaining a blood glucose signal by subtracting the second signal from the first signal, and calculating the amount of blood glucose in a subcutaneous blood vessel based on the obtained blood glucose signal. Moreover, fundamental blood glucose signals can be extracted in real time without collecting blood.
