CPC G01S 7/4808 (2013.01) [G01S 7/4816 (2013.01); G01S 17/10 (2013.01); G01S 17/89 (2013.01)] | 20 Claims |
1. A system for determining a first angle of an incident beam of a coherent light, the system comprising:
an optical antenna;
first waveguides communicably coupled to the optical antenna;
a manifold communicably coupled to the first waveguides;
second waveguides communicably coupled to the manifold;
pixels communicably coupled to the second waveguides; and
a processor,
wherein:
the pixels are arranged in an array and are configured to measure a power of the coherent light that emerges from the second waveguides, and
the processor is configured to operate a neural network trained to determine the first angle of the incident beam from an analysis of a distribution of the power across the array, wherein the pixels are inputs for the neural network and the neural network is configured to be trained by causing the incident beam of the coherent light to impinge the optical antenna at a known angle.
