description	Disclosed herein is a system for determining information about one or more defects on or in a test object. The system includes a light source configured to illuminate a test object with spatially coherent light; a multi-element detector positioned to detect an interference pattern of light associated with one or more defects on or in the illuminated test object; and an electronic control module in communication with the multi-element detector and configured to process the interference pattern to determine information about the one or more defects on or in the test object.
