The communication system in an embodiment includes a server apparatus. The server apparatus includes a controller that issues an instruction for executing priority control when a priority vehicle passes through a place where a roadside unit is installed. The priority control prioritizes a first communication performed by the priority vehicle via the roadside unit over a second communication performed by anything other than the priority vehicle via the roadside unit.

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. 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.

An illuminator according to the present disclosure includes a light source section and an optical phase modulator. The light source section emits light including first and second polarization components. The optical phase modulator generates and emits first illumination light (SDR illumination light) and second illumination light (HDR illumination light) The first illumination light is used in a light intensity modulator to generate an image in a first luminance region. The second illumination light is used in the light intensity modulator to generate an image in a second luminance region The optical phase modulator emits, as the first illumination light, light of the first polarization component without performing phase modulation. The optical phase modulator performs phase modulation on light of the second polarization component on the basis of the image in the second luminance region, and emits the phase-modulated light as the second illumination light.
