Abstract: A projector system including a projector unit and a control device. The projector unit includes: a projector; a change mechanism that changes a projection direction; a plurality of optical systems having different optical properties; and a switch mechanism that selects one of the optical systems. The control device includes: a change unit that controls the change mechanism; and a switch unit that causes the switch mechanism to place one of the optical systems to be used for the projector in conjunction with the changing of the projection direction of the projector which is caused by the change unit.

Abstract: A light deflection element is capable of deflecting incident light so as to follow a position of an observer and suppressing reduction in intensity of light that reaches eyes of the observer regardless of their position. The light deflection element includes: a first optical element configured to deflect incident light; a second optical element configured to change a deflection direction of emitted light by changing a refractive index thereof according to a voltage applied thereto; a third optical element; and a control section configured to control the voltage applied to the second optical element. At least one of interfaces between the first and second optical elements and the second and third optical elements is an aspheric surface. The aspheric surface has an optical power that compensates enlargement of the emitted light which is caused by refractive index distribution caused when a voltage is applied to the second optical element.
