  • Publication number: 20100321773
    Abstract: A method and system for three-dimensional polarization-based confocal microscopy are provided in the present disclosure for analyzing the surface profile of an object. In the present disclosure, a linear-polarizing structured light formed by an optical grating is projected on the object underlying profile measurement. By means of a set of polarizers and steps of shifting the structured light, a series of images with respect to the different image-acquired location associated with the object are obtained using confocal principle. Following this, a plurality of focus indexes respectively corresponding to a plurality of inspected pixels of each image are obtained for forming a focus curve with respect to the measuring depth and obtaining a peak value associated with each depth response curve. Finally, a depth location with respect to the peak value for each depth response curve is obtained for reconstructing the surface profile of the object.

  • Patent number: 6992293
    Abstract: This invention relates to a real-time infrared chemical imaging spectroscopic apparatus, including a light source for generating infrared radiation. A test sample absorbs a narrow-bandwidth infrared radiation as a result of a monochromator dispersing the infrared radiation and emits thermal radiation. IR camera collects the thermal radiation to form an image. As such, the present invention inspects the test sample in real time without a huge amount of complicated computation. Thus, the efficiency of inspection is increased and the optical design of the apparatus is more compact.

  • Patent number: 6972851
    Abstract: An approaching apparatus based on spectral shift is disclosed, which includes a broadband light source, an optical-guide unit, and an optical receiving unit. The broadband light source emits a broadband light with the first central wavelength to the optical-guide unit and illuminates a sample via a probe within the optical-guide unit. A generated broadband light of the second central wavelength goes back the optical-guide unit via the original optical path to reach the optical receiving unit. Then, the receiving unit calculates the distance between the probe and the sample based on the characteristic curve of the approaching distance vs. the deviation of the first central wavelength. The deviation is used for feedback control so that the displacement driver moves the probe to adjust the distance between the probe and the sample.

    Abstract: The invention provides an optical trapping skirt for adjusting the diameter of a beam passing thereof by varying the aperture. The optical trapping skirt has a body of bell shape and an iris diaphragm of bell shape, wherein the iris diaphragm of bell shape is installed inside the body so as to construct a ring like cavity. The undesired portion of the beam, which is incident on the iris diaphragm, is trapped in the ring like cavity and cannot be escaped. The aperture of the iris diaphragm is adjustable, so the diameter of the beam passing the optical trapping skirt is also controllable.
