  • Publication number: 20150002853
    Abstract: A miniature scan-free optical tomography system is provided. The system includes a broadband light source. A detection device is composed without a grating in front of it. A beamsplitter splits a light beam emitted from the broadband light source into a first reference light beam and a first sample light beam. An optical delay device including a fixed single curved reflecting surface reflects the first reference light beam into a second reference light beam having different optical path lengths only along a first dimension. The second reference light beam is incident through the beamsplitter to the detection device. A focusing device focuses the first sample light beam only along a third dimension. A second sample light beam reflected from the sample is incident to the detection device. Different portions of the second reference light beam along the first dimension have different optical path lengths.

  • Patent number: 8379220
    Abstract: The present invention provides an imaging and measuring apparatus for the surface and the internal interface of an object, which comprises a broadband wave source, a wave-splitting structure, a wave-delaying device, a reflecting component, and a sensor. The broadband wave source transmits a broadband incident wave. The wave-splitting structure splits the broadband incident wave into a first incident beam, a second incident beam, and a third incident beam. The first incident beam is illuminated on an object under test, which reflects a measuring beam. The wave-delaying device receives the second incident beam and reflects a reference beam. The reflecting component receives the third incident beam and reflects a calibration beam. The sensor receives a first interference signal of the measuring beam and the reference beam, and a second interference signal of the reference beam and the calibration beam.

  • Patent number: 7920269
    Abstract: A system and method for measuring interferences are disclosed. The system is based on the concept of a composite interferometer. The sample is measured while a simultaneous compensation of the phase deviation due to the relative displacement of the optical delay component between the measurements at different pixels of the sample is performed. In the application of profilometry, the information of the surface profile of a material is obtained from the phase shift of the interference signal. By using the proposed compensation mechanism, an axial resolution at nanometer scale can be achieved. For the measurement of a thin film, a polarized probe beam is oblique incident on the sample. The system can perform a simultaneous measurement of the refractive index and the thickness of the thin film. From the ratio of the intensities of the interferograms of TE and TM waves as well as the phase shifts of the interferograms, the refractive index and the thickness of the thin film can then be obtained simultaneously.

  • Patent number: 7576933
    Abstract: This invention provides a system and a method of the optical delay line, wherein the system comprises a source and an array of mirrors, wherein the array of mirrors comprises a first reflective mirror, a second reflective mirror, a third reflective mirror, and a fourth reflective mirror. Beams from the source could be delayed because the beams are multi-reflected by the reflective mirrors.
