The image data generator generates image data. The controller generates a gradation control signal based on the image data. The liquid crystal element includes a first substrate and a light receiver. The first substrate has a pixel region in which a plurality of pixel electrodes constituting pixels are arranged. The light receiver photoelectrically converts light with which the pixel region is irradiated to generate a light reception signal. The light reception signal detector generates a drive control signal based on the light reception signal. The liquid crystal element changes an inclination angle of a wavefront of the light with which the pixel region is irradiated by applying different driving voltages to the plurality of pixel electrodes based on the gradation control signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal element, phase modulation device, and control method of liquid crystal element","description":"A phase modulation device includes an image data generator, a controller, a light reception signal detector, and a liquid crystal element.
