  • Patent number: 10317197
    Abstract: A system and method for shape sensing with optical fiber include collecting (610) shape data from a shape sensing optical fiber device. The shape data are tested (620) to determine data positions that exceed an acceptable threshold based on geometrical expectations of the shape data. The shape data corresponding to the data positions that exceed an acceptable threshold are rejected (640). Acceptable shape data are rendered (650) to provide a stable shape sensing data set.

  • Patent number: 10260947
    Abstract: A system and method of dynamically localizing a measurement of parameter characterizing tissue sample with waves produced by spectrometric system at multiple wavelengths and detected at a fixed location of the detector of the system. The parameter is calculated based on impulse response of the sample, reference data representing characteristics of material components of the sample, and path lengths through the sample corresponding to different wavelengths. Dynamic localization is effectuated by considering different portions of a curve representing the determined parameter, and provides for the formation of a spatial map of distribution of the parameter across the sample. Additional measurement of impulse response at multiple detectors facilitates determination of change of the measured parameter across the sample as a function of time.

  • Patent number: 10256104
    Abstract: The present invention relates to a film-thickness measuring method for detecting a film thickness by analyzing optical information contained in a reflected light from a substrate. The film-thickness measuring method includes producing a spectral waveform indicating a relationship between intensity and wavelength of reflected light from a substrate; performing Fourier transform processing on the spectral waveform to determine strengths of frequency components and corresponding film thicknesses; determining local maximum values (M1, M2) of the strengths of the frequency components; and selecting, according to a preset selection rule, one film thickness from film thicknesses (t1, t2) corresponding respectively to the local maximum values (M1, M2). The selection rule is either to select an N-th largest film thickness or to select an N-th smallest film thickness, and N is a predetermined natural number.

  • Patent number: 10215704
    Abstract: Described herein are technologies to facilitate computed tomographic techniques to help identifying chemical species during plasma processing of a substrate (e.g., semiconductor wafer) using optical emission spectroscopy (OES). More particularly, the technology described herein uses topographic techniques to spatially resolves emissions and absorptions in at least two-dimension space above the substrate during the plasma processing (e.g., etching) of the substrate. With some implementations utilize optical detectors positioned along multiple axes (e.g., two or more) to receive incident incoming optical spectra from the plasma chamber during the plasma processing (e.g., etching) of the substrate. Because of the multi-axes arrangement, the incident incoming optical spectra form an intersecting grid.
