1. An optical device, comprising:
a radiation source, which is configured to emit a beam of light; and
a scanning cell positioned to receive the beam of light and comprising:
transparent entrance and exit faces, at least one of the faces comprising a flexible membrane;
a transparent fluid contained between the entrance and exit faces, so that the beam enters the transparent fluid through the entrance face and exits the transparent fluid through the exit face; and
at least one actuator coupled to the flexible membrane, and configured, responsively to an applied electrical signal, to apply an asymmetrical deformation to the flexible membrane, thereby deflecting the beam by refraction in the transparent fluid.
