Abstract
An optical device includes an optical element including a liquid crystal cell configured to distribute light emitted from a light source, a power supply part configured to generate first and second potentials, a control signal generation circuit part configured to generate a control signal that controls a pulse width of each of the first and second potentials, and a switch circuit part configured to output a first potential signal including the first potential with a first pulse width and the second potential with a second pulse width based on the control signal. The liquid crystal cell includes a first substrate on which first and second transparent electrodes are alternately arranged in a first direction, and a second substrate on which third and fourth transparent electrodes are alternately arranged in a second direction. The first potential signal is input to the first transparent electrode.
