Abstract
Planar optical module (100, 100′) for capturing, converging and collimating incident light (3, 3′) with a variable incident direction comprising: —a first optical arrangement (10) with an optical layer able to converge the incident light-beam (3, 3′), forming thereby a converging light-beam (4, 4′) and —a second optical arrangement (20) placed downstream said first optical arrangement (10), said second optical arrangement (20) having an optical layer collimating said converging light-beam(s) (4, 4′), forming thereby a collimated and concentrated beam (5, 5′), wherein the first and second optical arrangements (10, 20) are movable one relative to the other such that the relative position of first and second optical arrangements (10, 20) allows said collimated and concentrated beam (5, 5′) to have an orientation which is, in a plane perpendicular to the main plane (P) of the planar optical module (100, 100′), predetermined, fixed and independent from the direction of the incident light (3, 3′). Preferentially, the first optical arrangement (10) comprises two optical layers (11, 12) movable one relative to the other, the second optical arrangement (20) comprises either an optical layer…
