Abstract
An optical deflection apparatus includes a pair of transparent electrodes, a liquid crystal layer, put between the transparent electrodes, in which stripes are formed at intervals based on a waveform of a driving signal supplied to the pair of transparent electrodes, the stripes functioning as a grating by which incident light is deflected in a deflecting direction, and a driving unit for supplying to the pair of transparent electrodes the driving signal having a waveform by which the deflecting direction changes with time.
