Abstract: An optical scanning system includes a radiating source capable of outputting a source light beam, a de-scan lens that is configured to output a de-scanned light beam, the de-scan lens is located approximately one focal length of the de-scan lens from a sample irradiation location, a focusing lens that is configured to output a focused light beam, a first non-polarizing beam splitter configured to be irradiated by at least a portion of the focused light beam, a second non-polarizing beam splitter configured to be irradiated by at least a portion of the focused light beam that is reflected by the first non-polarizing beam splitter, and a detector that is located at approximately one focal length of the focusing lens from the focusing lens, the detector is configured to be irradiated by at least a portion of the focused light beam that is reflected by the second non-polarizing beam splitter.

Abstract: An optical scanning system including a radiating source that outputs a light beam, a time varying beam reflector that reflects the light beam through a scan lens towards a transparent sample at an incident angle of plus or minus ten degrees from Brewster's angle, a focusing lens configured to be irradiated by light scattered from the transparent sample, and a detector that is irradiated by the light scattered from the transparent sample. The detector outputs a signal that indicates an intensity of light measured by the detector. None of the light scattered from the transparent sample is blocked. The light scattered from the transparent sample is scattered from the top surface of the transparent sample, the bottom surface of the transparent sample, or any location in between the top surface of the transparent sample and the bottom surface of the transparent sample.

Abstract: An optical scanning system includes a first radiating source capable of outputting a first source light beam, a second radiating source capable of outputting a second source light beam, a first time-varying beam reflector configured to direct the first source light beam and the second source light beam toward the sample, a scan lens configured to focus the first source light beam and the second source light beam reflected by the first time-varying beam reflector onto the sample, and a compound ellipsoidal collector configured to direct light scattered from the sample toward a scattered radiation detector. The optical scanner causes one of the first or second source light beams to be directed towards a sample at an incident angle. The first light beam has a first wavelength, the second light beam has a second wavelength, and the first wavelength and the second wavelength are not the same.

Abstract: An optical scanning system, including: a radiating source that outputs a light beam, a first time varying beam reflector that reflects the light beam through a scan lens towards a transparent sample, a second time varying beam reflector that reflects the light beam reflected from the transparent sample, a focusing lens that focuses the light beam reflected from the transparent sample, a blocker, and a detector that is irradiated by the one or more selectable portions of the light beam reflected from the transparent sample that pass the blocker. The blocker can be configured to block one or more portions of the light beam reflected from the transparent sample so that one or more selectable portions of the light beam reflected from the transparent sample can pass the blocker.
