Abstract

A light beam adjusting device includes a first optical deflection unit having a first light incidence face and a first light exit face, the first optical deflection unit being arranged to deflect light which is incident from the first light incidence face and which exits from the first light exit face at a first deflection angle. A second optical deflection unit has a second light incidence face and a second light exit face, the second light incidence face being arranged to face the first light exit face and including an array of prisms arranged to deflect the light exiting from the first light exit face at a second deflection angle. The light beam adjusting device obtains the desired deflection direction of the incident light beam by a compact structure providing two-stages of optical deflection units to achieve the deflection of an incident light beam.
