Claim 3:
4. The imaging subsystem according to claim 1, wherein the optical phased array (OPA) comprises (i) a first layer of a first optical material, and (ii) a second layer of a second optical material,
wherein the first layer comprises a first array of first antennas consisting of a material selected froth the group consisting of a phase transition material, a phase change material, and a second harmonic (SH) generation material, wherein a first spatial separation between the first antennas of the first array of the first antennas is a uniform spatial separation, or a non-uniform spatial separation,
wherein each antenna of the first array of the first antennas is passively controlled, or actively controlled by an electrical stimulus, or an optical stimulus,
wherein the second layer comprises a second array of second antennas consisting of a material selected from the group consisting of the phase transition material, the phase change material, and the second harmonic (SH) generation material, wherein a second spatial separation between the second antennas of the second array of the second antennas is a uniform spatial separation, or a non-uniform spatial separation,
wherein each antenna of the second array of the second antennas is passively controlled, or actively controlled by the electrical stimulus, or the optical stimulus,
wherein the first layer of the first optical material, and the second layer of the second optical material are electrically isolated by an electrically insulating layer.
