Patent ID: 7373049

Claim:
An optical deflection matrix comprising: at least two optical deflection modules each configured to provide: from an incoming light beam having a given direction of propagation an outgoing light beam having a direction of propagation taken in a first set of potential directions, or from an incoming light beam having a direction of propagation taken in a second set of potential directions an outgoing light beam having a given direction of propagation, wherein each optical deflection module comprises an own single deflection element of the incoming light beam configured to assume plural potential positions that are in relation to the potential directions of the first set or of the second set and two fixed return elements positioned on either side of the deflection element, a main potential position of the deflection element leading to a principal direction of the first set or of the second set, the principal direction being colinear with the given direction of propagation of the incoming light beam or of the outgoing light beam, the principal directions of the optical deflection modules being located in a same plane.
