1. A machine vision system, comprising:

  • at least one patterned area light source;

    at least one digital camera oriented at a first angle relative to surface of an object to be inspected, wherein the at least one patterned area light source is oriented at a second angle relative to the surface of the object to be inspected such that a field of view of the at least one digital camera encompasses reflection of at least a portion of light emitted by the at least one patterned area light source from the surface of the object to be inspected;

    a digital image data receiving module stored on a memory of a computing device that, when executed by a processor of the computing device, causes the processor to receive digital image data from the at least one digital camera, wherein the digital image data is representative of the reflection of at least a portion of light emitted by the at least one patterned area light source from the surface of the object to be inspected; and

    .a phase measuring deflectometry module stored on the memory of the computing device that, when executed by the processor of the computing device, causes the processor to determine whether the surface of the object to be inspected includes a defect based on the digital image data.
