With configuration of an optical sensor disposed on a displacement platform and in cooperation with a broadband light source and an optical spectrum analyzer, when the displacement platform moves, the waveguide grating of the optical sensor is resonated and the reflected light provided with a resonance wavelength is formed. The waveguide grating has the plurality of grating periods, and when the displacement platform moves to a different position to make the broadband light source correspond to a different grating period, the position can correspond to the different resonance wavelength. Therefore, according to the aforementioned configuration, the position is determined according to the different resonance wavelength, instead of using an optical encoder; furthermore, the micrometer-scale or nanometer-scale displacement detection is achieved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical displacement sensing system","description":"An optical displacement sensing system is provided.
