The optical section includes a light-incident surface on which light is incident. The moving section supports the optical section and the shaft section swingably supports the moving section. The actuator swings the moving section based on a drive signal having a trapezoidal waveform. A swing waveform representative of a trajectory of the moving section as the moving section is swung has a trapezoidal waveform. A maintenance time of a flat portion of the trapezoidal waveform of the drive signal is shorter than a maintenance time of a flat portion of the trapezoidal waveform of the swing waveform of the moving section."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical device and image display device","description":"An optical device includes an optical section, a moving section, a shaft section, and an actuator.
