1. 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,
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 first set of computer implementable instructions to calculate, or compute Lorentzian Least Squares Fit (LLSF), wherein the first set of computer implementable instructions is stored in one or more non-transitory storage media,
(b) an optical phased array (OPA) for laser beam steering,
wherein the optical phased array (OPA) for laser beam steering 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 second set of computer implementable instructions to detect, or image an object in fog, or rain, or snow; and
wherein the second set of computer implementable instructions at least includes an image reconstruction instruction,
wherein the second set of computer implementable instructions is stored in the one or more non-transitory storage media,
(ii) a near real time map, or an augmented reality (AR) enhanced near real time map, viewed on a display, or a head-up display (HUD).
