A non-invasive imaging and analysis system suitable for measuring concentrations of specific components, such as blood glucose concentration and suitable for non-invasive analysis of defects or malignant aspects of targets such as cancer in skin or human tissue, includes an optical processing system which generates a probe and composite reference beam. The system also includes a means that applies the probe beam to the target to be analyzed and modulates at least some of the components of the composite reference beam by means of a micro-mirror array, such that signals corresponding to different depths within the target can be separated by electronic processing. The system combines a scattered portion of the probe beam and the composite beam interferometrically to concurrently acquire information from multiple depths within a target. It further includes electronic control and processing systems.
