wherein the second reflector is configured to at least partially reflect the light beam propagated through the first reflector back to the first reflector;
wherein the first reflector is further configured to at least partially reflect the light beam reflected by the second reflector back to the second reflector;
wherein the second reflector is further configured to at least partially transmit the light beam reflected by the first reflector;
wherein at least one of the first or second reflectors is deformable by application of a control signal for tuning optical power of the lens; and
