Filed:

Aug 20, 2019

Appl. No.:

16/545154

Inventors:

- Baltimore MD, US

David W. Blodgett - Ellicott City MD, US

International Classification:

G01N 21/47

Abstract:

An optical receiver is provided that includes an array of photoreceivers. Each photoreceiver may be configured to receive a respective portion of a speckle pattern generated by interaction between an object beam and a scattering medium and each photoreceiver may be configured to generate respective electrical detection signals for provision to processing circuitry for summing of the electrical detection signals. A photoreceiver may include a collector, first detector and second detectors, and first and second optical splitters. The photoreceiver may be configured to generate a first electrical detection signal and a second electrical detection signal based on a received portion of the speckle pattern.

Abstract:

Example apparatuses and methods relating to imaging systems are provided. An example imaging system may include an optical source configured to generate an optical beam, a beam splitter configured to split the optical beam into a reference beam and an object beam, and a beam combiner configured to route a combined beam with reference beam and object beam components along a common path into a target medium. In this regard, the target medium may act upon the combined beam to form a common path interference beam. The example imaging system may further include an imaging sensor configured to receive the common path interference beam and generate common path interference beam data associated with the common path interference beam, and an image data processor configured to analyze the common path interference beam data to generate image data describing the target medium.
