Abstract

See full text

An object is to provide a light deflection device and an optical device having a simple structure suitable for reducing the size and weight where a deflection angle can be increased. The light deflection device includes: a light deflection element that deflects incident light in one in-plane direction to be emitted; a driving unit that drives the light deflection element; a light collecting element that is disposed on a light emission side of the light deflection element; and an angle increasing optical element consisting of a diffraction element in which a periodic structure pitch gradually changes from a center of deflection of the light deflection element toward an outer side.
