Claim 56:
57. 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 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,
wherein at least one of the one or more lasers is communicatively interfaced with a Lorentzian Least Squares Fitting Processor (LLSF Processor),
wherein the Lorentzian Least Squares Fitting Processor (LLSF Processor) comprises (i) an integrated electronic circuit (IC), and (ii) a set of computer implementable instructions to calculate, or compute Lorentzian Least Squares Fit (LLSF), wherein the set of computer implementable instructions is stored in one or more non-transitory storage media,

(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
a photonic neural learning processor (PNLP) for photonic neural processing, wherein the photonic neural learning processor (PNLP) comprises:
(i) an interferometer, and a laser,
or
(ii) one or more phase transition material based optical switches, or one or more phase change material based optical switches,
wherein at least one of the one or more phase transition material based optical switches is electrically, and/or optically controlled,
wherein at least one of the of one or more phase change material based optical switches is electrically, or optically controlled.
