  • Patent number: 11410842
    Abstract: Apparatus and method for processing an image-charge/current signal for an ion(s) undergoing oscillatory motion within an ion analyser apparatus. The method comprises: obtaining a recording of the image-charge/current signal (20a-20e) in the time domain. Then, by a signal processing unit, a value for the period (T) of a periodic signal component is determined within the recorded signal. Subsequently, the recorded signal is segmented into a number of successive time segments [0;T] of duration corresponding to the period (T). These lime segments are then co-registered in a first time dimension (t1) defining the period (T). The co-registered time segments are then separated along a second time dimension (t2) transverse to the first time dimension (t1). This generates a stack of time segments collectively defining a 2-dimensional (2D) function. The 2D function varies both across the stack in the first time dimension and along the stack in the second time dimension.

  • Patent number: 11371937
    Abstract: Apparatus and methods for fluorescence imaging using radiofrequency multiplexed excitation. One apparatus splits an excitation laser beam into two arms of a Mach-Zehnder interferometer. The light in the first beam is frequency shifted by an acousto-optic deflector, which is driven by a phase-engineered radiofrequency comb designed to minimize peak-to-average power ratio. This RF comb generates multiple deflected optical beams possessing a range of output angles and frequency shifts. The second beam is shifted in frequency using an acousto-optic frequency shifter. After combining at a second beam splitter, the two beams are focused to a line on the sample using a conventional laser scanning microscope lens system. The acousto-optic deflectors frequency-encode the simultaneous excitation of an entire row of pixels, which enables detection and de-multiplexing of fluorescence images using a single photomultiplier tube and digital phase-coherent signal recovery techniques.

  • Patent number: 11164720
    Abstract: To measure a depth of a three-dimensional structure, for example, a hole or a groove, formed in a sample without preparing information in advance, an electron microscope detects, among emitted electrons generated by irradiating a sample with a primary electron beam, an emission angle in a predetermined range, the emission angle being formed between an axial direction of the primary electron beam and an emission direction of the emitted electrons, and outputs a detection signal corresponding to the number of the emitted electrons detected. An emission angle distribution of a detection signal is obtained based on a plurality of detection signals, and an opening angle is obtained based on a change point of the emission angle distribution, the opening angle being based on an optical axis direction of the primary electron beam with respect to the bottom portion of the three-dimensional structure.

  • Patent number: 11159738
    Abstract: An imaging device may include single-photon avalanche diodes (SPADs). To improve the sensitivity and signal-to-noise ratio of the SPADs, photon detection efficiency (PDE) may be increased. However increased photon detection efficiency may result in a decreased saturation rate and lower than desired dynamic range. To increase the dynamic range, a SPAD-based semiconductor device may operate with multiple sub-exposures. During the first sub-exposure, an over-bias voltage may be set to a first voltage level so that the SPADs have a first photon detection efficiency. During the second sub-exposure, the over-bias voltage may be set to a second voltage level so that the SPADs have a second photon detection efficiency that is different than the first photon detection efficiency. Image data from the first and second sub-exposures may then be combined into a single high dynamic range depth map.

  • Patent number: 11112391
    Abstract: A degree of similarity in the peak pattern between a mass spectrum obtained for an unknown target substance in a sample and a mass spectrum of a known specific substance is calculated (S4). If the degree of similarity is within a range of 80-60% (“No” in S6), the ratio between the signal intensities at two mass-to-charge ratios characteristic of the specific substance is calculated and compared with a reference value (S7 and S8). If the intensity ratio exceeds the reference value, the target substance is likely to be the specific substance. Therefore, as in the case where the degree of similarity is equal to or higher than 80%, it is concluded that the specific substance is contained in the sample (S10).
