Abstract: PURPOSE:To provide an optical deflector capable of efficiently imparting deflection to light at a high speed and efficiently obtaining deflected output light. CONSTITUTION:The input light which is linearly polarized light deflected in a z-axis direction and progresses in a y-direction is inputted to a polarization beam splitter 100 and transmits the splitter in the state of rectilinearly polarized light. The light is outputted from the splitter and is inputted to an electrooptical crystal 200 and is subjected to primary deflection during the passage. The primarily deflected light is rotated in the plane of deflection by passing a quarter- wave plate 300 until the light arrives at a reflection mirror 410. The light is reflected in the direction approximately opposite to the input direction and is again passed through the quarter-wave plate 300, by which the linearly polarized light having the deflection direction in approximately the x-axis direction is obtd. The light is inputted to the optical crystal 200 and is further subjected to secondary deflection during the transmission. The secondarily deflected light is reflected approximately to a right angle by the polarization beam splitter 100 and is outputted.
