The phase modulator according to the present disclosure includes a light phase modulation element that has a plurality of pixels arranged with the pixel pitches p being different from each other to have a pixel structure suppressing occurrence of high-order diffraction light and that modulates a phase of light with respect to each of the pixels. Moreover, the phase modulator according to the present disclosure includes a capturing optical system that captures a plurality of fluxes of high-order diffraction light generated in each of the pixels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Phase modulator, lighting system, and projector","description":"An object of the present disclosure is to provide a phase modulator, a lighting system, and a projector that allow for improving diffraction efficiency in a light phase modulation element.
