CONTROLLABLE LIGHT DEFLECTION DEVICE WITH REDUCED ABERRATION

The invention relates to a variable light deflection device comprising a prism, a reflection member arranged opposite to one of the faces of the prism for deflecting an incident refracted light ray back into the prism through said face as a deflected light ray, a refraction member arranged opposite another face of the prism for refracting the deflected light ray transmitted through said other face into a refracted output light ray, first and second transparent, shape variable bodies arranged between prism faces and the reflection and refraction members, first and second actuator systems arranged to tilt the reflection member to change a first propagation deviation angle of the refracted output light ray in a first output plane, and where the second actuator system is arranged to tilt the refraction member to change the same first propagation deviation angle of the refracted output light ray in said first output plane.
