Systems and methods for multi-function coherent imaging

A method for multi-function coherent imaging, comprising:

• outputting, with a first coherent radiation source, a first radiation beam;
• outputting, with a second coherent radiation source, a second radiation beam;
• directing, with one or more first optical components, at least a portion of the first radiation beam toward a first detector;
• directing separately at least a portion of the second radiation beam towards the first detector, wherein at least a portion of the second radiation beam is spatially offset, angularly offset, or spatially and angularly offset from at least a portion of the first radiation beam;
• combining, with one or more second optical components, at least a portion of the first radiation beam and at least a portion of the second radiation beam to form a first composite beam;
• directing, with the one or more second optical components, the first composite beam towards an object to be imaged;
• combining, with the one or more first optical components and the one or more second optical components, at least a portion of the first radiation beam directed toward the first detector, at least a portion of the second radiation beam directed toward the first detector, and at least a portion of a first return radiation from the object in a first instance at the first detector;
• and
• simultaneously recording, with the first detector, a first superposition of a first intensity pattern and a second intensity pattern, wherein the first intensity pattern is an intensity pattern of a first interference between at least a portion of the first radiation beam and at least a portion of the first return radiation from the object, wherein the second intensity pattern is an intensity pattern of a second interference between at least a portion of the second radiation beam and at least a portion of the first return radiation from the object.
