Claim 57:
58. An imaging subsystem,
wherein the imaging subsystem is a coherent subsystem,
wherein the imaging subsystem is based on frequency modulation (FM), and/or amplitude modulation (AM),
the imaging subsystem comprising:
(a) (i) one or more lasers, and (ii) one or more first photodiodes (PDs), or one or more balanced photodiodes (BPDs); and
wherein at least one of the one or more lasers has a distinct wavelength, or a tunable wavelength,
wherein at least one of the one or more lasers has a laser linewidth less than 200 Hz,

(b) an optical component selected from the group consisting of an optical phased array (OPA), an optical switch, an antenna and a metamaterial surface,
wherein the optical phased array (OPA) is a two-dimensional (2-D) optical phased array (OPA), or a three-dimensional (3-D) optical phased array (OPA),

wherein the imaging subsystem is communicatively interfaced with:
(i) a first set of computer implementable instructions to detect, or image an object in fog, or rain, or snow; and
wherein the first set of computer implementable instructions at least includes an image reconstruction instruction,
wherein the first set of computer implementable instructions is stored in the one or more non-transitory storage media,

(ii) a second set of computer implementable instructions comprising artificial intelligence, or machine learning, or deep learning,
wherein the second set of computer implementable instructions is stored in the one or more non-transitory storage media.
