Abstract
Disclosed herein a spectral device with enhanced stability of optical sensor and an operating method of the device. According to an embodiment of the present disclosure, there is provided a spectral device including: a light splitter configured to split an incident light into a reference light and a signal light; at least one beam shutter configured to perform control for selectively outputting at least one of the reference light and the signal light and for blocking the two signals together; and a controller configured to provide an absorption property of a bio-material by comparatively quantizing an intensity of the reference light and an intensity of the signal light, which are received into a sensor through the beam shutter.
