  • Patent number: 11867626
    Abstract: Apparatus and methods for complex imaging reflectometry and refractometry using at least partially coherent light. Quantitative images yield spatially-dependent, local material information about a sample of interest. These images may provide material properties such as chemical composition, the thickness of chemical layers, dopant concentrations, mixing between layers of a sample, reactions at interfaces, etc. An incident beam of VUV wavelength or shorter is scattered off of a sample and imaged at various angles, wavelengths, and/or polarizations. The power of beam is also measured. This data is used to obtain images of a sample's absolute, spatially varying, complex reflectance or transmittance, which is then used to determine spatially-resolved, depth-dependent sample material properties.

  • Patent number: 11841357
    Abstract: A measurement apparatus of a moving paper web, includes an optical radiation source that outputs optical radiation toward a scattering element of the measurement apparatus. The scattering element scatters the optical radiation, and a transmitting surface of the scattering element directs the optical radiation in a scattered manner toward the moving paper web. A distance between said transmitting surface of the scattering element and a surface of the paper web is known, and the transmitting surface and a detector of the apparatus are on opposite sides of the paper web. The detector receives at least a part of the optical radiation, which is side-scattered from the moving paper web. The detector determines a moisture value and a dry weight of the paper web on the basis of spectral information on the received optical radiation and the known distance.

  • Patent number: 11830329
    Abstract: A method for testing a value document having a luminescence feature involves guiding the value document past a test sensor in a transport direction. A scanning sequence occurs that repeats itself multiple times upon guiding the value document past the test sensor. The method involves irradiating a test region of the test sensor such that the test radiation is arranged to be remitted by the value document at least partially in a detection spectral range of the test sensor. Excitation radiation is arranged to cause an emission radiation of the luminescence feature in the detection spectral range. The method further involves scanning at least one location-dependent remission spectral value in the test region in the first irradiation phase, irradiating the test region only with the excitation radiation in a second irradiation phase, and scanning at least one location-dependent emission spectral value in the test region after the first irradiation phase.

  • Patent number: 11346790
    Abstract: The light from an optical metrology device is focused into a measurement spot on a sample using a focusing system. The focusing system uses an image of the light reflected from the measurement spot to determine a best focal position at a desired position of the sample. The focusing system selects a characteristic of reflected light, such as polarization state or wavelengths, to use for focusing. The characteristic of the reflected light that is selected for use in determining focal position is affected different by different portions of the sample. For example, light reflected from a top surface of a sample may have a different characteristic than light reflected by an underlying layer. The selected characteristic of the reflected light is used by the focusing system to focus the measurement spot at the top surface or an underlying layer of the sample.

  • Patent number: 11049993
    Abstract: The present invention adopts an aluminum nitride substrate with great heat dissipation, great thermal conductivity, high electrical insulation, long service life, corrosion resistance, high temperature resistance, and stable physical characteristics. A high-quality zinc oxide film with a wide energy gap is fabricated on the aluminum nitride substrate by magnetron radio frequency (RF) sputtering. Compared with general vapor deposition, chemical vapor deposition and hydrothermal, the magnetron RF sputtering grows the high-quality zinc oxide film with few defects. The zinc oxide film with few defects concentration is an important key technology for short-wavelength optoelectronic devices, which decrease leakage currents of the optoelectronic devices, reduces flicker noise, and further improves its UV-visible rejection ratio.

  • Patent number: 10908129
    Abstract: In quartz-enhanced photoacoustic spectroscopy (QEPAS), an analyte (typically in gas phase) generates a pressure wave in response to incident laser light. A quartz tuning fork (QTF) resonant at the frequency of the pressure wave transduces the pressure wave into an electrical signal. Pulsing the laser briefly reduces the amount of thermal chirp and increases the fraction of time that the laser emits at the wavelength(s) of interest. This increases the measurement efficiency. Pulsing the incident laser light with bursts of short pulses at the QTF resonant frequency increases signal strength. Exciting the sample with a two pulses at different laser wavelengths, separated by a half QTF period yields signal and background acoustic waves that partially cancel when integrated by the QTF, producing a differential measurement. Pulsing the incident laser light at a frequency faster than the gas response cut off frequency can improve the noise performance of a QEPAS measurement.
