Optical deflection device and distance measurement device

Abstract

An optical deflection device includes a first mirror unit, a second mirror unit, and a support unit. The first mirror unit includes a first mirror surface that is a reflection surface that reflects light. The second mirror unit is opposed to the first mirror unit and includes a second mirror surface that is a reflection surface that reflects light. The support unit couples the first mirror unit and the second mirror unit while supporting the first mirror unit and the second mirror unit in a swingable manner about a movable axis. The first mirror surface and the second mirror surface are respectively disposed on surfaces different from surfaces at which the first mirror unit and the second mirror unit are coupled to the support unit.
