  • Patent number: 11143555
    Abstract: In a spectrometry setup where a first spectral component dominates a second spectral component having a different wavelength, diffraction of the first spectral component as it passes through the optical train of the spectrometer can produce spectral noise that obscures detection of the second spectral component. To reduce the spectral noise, the light from the spectrometer is subject to spatial filtering or interference such that effects of the first spectral component are removed, or at least reduced. The second spectral component can then be more readily detected by a detector after the spatial filtering or interference. In embodiments, the spatial filtering or interference may be provided by a filtering module, which may be installed in existing spectrometry setups or form part of a unitary spectrometry system.

  • Patent number: 11015975
    Abstract: Disclosed herein is an all-digital phase and timing correction procedure for coherent averaging in dual-comb and multiheterodyne spectroscopy—applicable to any dual-comb spectroscopy setup. It can account for large frequency/phase instabilities of the used sources, yielding a significant reduction of the noise pedestal and an increase in signal-to-noise ratio (SNR) of the radio frequency (RF) beat notes. This technique is computationally efficient and can be conveniently implemented either as a post-processing algorithm or in a real-time data acquisition and processing platform without the necessity of adding any additional optical elements to the dual-comb spectroscopy system. By implementing this technique, the performance of any comb- or comb-like-source-based DCS system with a sufficient degree of mutual coherence between the optical modes can be improved in terms of SNR and number of spectroscopically-usable RF beat notes.

    Abstract: Conventional etalon based spectrometers have either a limited range of evaluation wavelengths or require continuous scanning of the etalon.

An improved optical spectrometer includes a cylindrical lens configured to converge the input beam of light in only one direction, whereby the input beam of light is focused along a focal line. Accordingly, a first etalon receives the input beam of light, and transmits a series of sub-beams, each sub-beam transmitted at a different angle from the normal, and each sub-beam including multiple frequencies based on the FSR, whereby a secondary dispersive element receives each sub-beam, and disperses each sub-beam into individual frequencies.

  • Patent number: 10644806
    Abstract: An heterodyne apparatus and method for measuring performance parameters of a coherent optical receiver at RF frequencies is disclosed. Two coherent lights are launched into signal and LO ports of the receiver with an optical frequency offset f. One of the lights is modulated in amplitude at a test modulation frequency F. COR performance parameters are determined by comparing two frequency components of the COR output. CMRR is determined based on a strength of a direct detection spectral line at the modulation frequency relative to that of spectrally-shifted lines at (F±f). GDV information is obtained by modulating one of the lights at two phase-locked frequencies, such as F and 2F, and comparing phases of two time-domain traces corresponding to frequency components of the COR output signal at the two frequencies.

  • Patent number: 10613309
    Abstract: In the microscope, an optical path and optical path of an image forming system are set so as to be perpendicular to each other when viewed from the top. In other words, in this microscope, there exists an ocular optical system that guides light, which propagates the optical path to optical path of the image forming system, to a user. The optical path is formed in a direction perpendicular to a direction of the light from a sample emitted from the ocular optical system to the user.

  • Patent number: 10608002
    Abstract: A system for object reconstruction includes an illuminating unit, comprising a light source and a generator of a non-periodic pattern. A diffractive optical element (DOE) is disposed in an optical path of illuminating light propagating from the illuminating unit toward an object, thereby projecting the non-periodic pattern onto an object. An imaging unit detects a light response of an illuminated region and generating image data indicative of the object within the projected pattern. A processor reconstructs a three-dimensional (3D) map of the object responsively to a shift of the pattern in the image data relative to a reference image of the pattern.

The test system may have a tunable light source with light-emitting diodes that are turned on in sequence while gathering measured responses from the detectors. Numerical optimization techniques may be used to produce final versions of the spectral responses for the light detectors from the measured responses and corresponding calibration data that is stored in the electronic device.
