Abstract
Generally discussed herein are systems, apparatuses, and methods that can detect a defect in a die. According to an example, a method can include transmitting a first beam of light with a wavelength and optical power configured to produce a reflected beam with at least one milli-Watt of power, linearly polarizing the first beam of light in a specific direction, circularly polarizing the linearly polarized light by a quarter wavelength to create circularly polarized light, directing the circularly polarized light to a device under test, linearly polarizing light reflected off the device under test by a quarter wavelength, or creating an image of the linearly polarized light reflected off the device under test.
