<p>A micro spectrometer (1) capable of receiving zero order spectral component (SO0) and first order spectral component (SO1) comprises an input part (10) for receiving optical signals, a micro diffraction grating (20) and a light sensor (30). The diffraction grating (20) has a focusing curved surface (23) and diffraction patterns (24) formed on the focusing curved surface (23), receives optical signals (SO) and separates the optical signals (SO) into a plurality of spectral components including the zero order spectral component (SO0) and the first order spectral component (SO1). The light sensor (30) has a first sensing portion (32) and a second sensing portion (34), and receives the spectral components separated and focused by the diffraction grating (20). The first sensing portion (32) receives the zero order spectral component (SO0), and the second sensing portion (34) receives the first order spectral component (SO1).</p> |
