A neural imaging system may include an imaging array, an image data processor operably coupled to the imaging array to process image data received from the imaging array, and a beam angle separator disposed between the imaging array and an object being imaged. The beam angle separator may be configured to separate an object beam reflected from the object being imaged into a plurality of reference beams each having different angular separation with respect to the object beam. The image data processor may be configured to generate image data of the object for each one of the reference beams to correspond to a respective different depth within the object.
