Abstract
Systems and methods are provided for multi-function coherent imaging comprising directing a first coherent radiation beam and a second coherent radiation beam towards a detector, where the second coherent radiation beam is spatially offset, angularly offset, or spatially and angularly offset from the first coherent radiation beam. A portion of the first coherent radiation beam and a portion of the second coherent radiation beam may be combined to form a composite beam. An object may be radiated with the composite beam. A first intensity pattern may be formed by interfering with return radiation from the radiated object with the first coherent radiation beam and a second intensity pattern is formed with the return radiation from the radiated object and the second coherent radiation beam. A detector may simultaneously record a superposition of the first intensity pattern and the second intensity pattern.
