摘要： A spectral imaging device (12) for generating an image (13A) of a sample (10) includes (i) an image sensor (30); (ii) a tunable light source (14) that generates an illumination beam (16) that is directed at the sample (10); (iii) an optical assembly (22) that collects light from the sample (10) and forms an image of the sample (10) on the image sensor (30); and (iv) a control system (32) that controls the tunable light source (14) and the image sensor (30). During a time segment, the control system (32) (i) controls the tunable light source (14) so that the illumination beam (16) has a center wavenumber that is modulated through a first target wavenumber with a first modulation rate; and (ii) controls the image sensor (30) to capture at least one first image at a first frame rate. Further, the first modulation rate is equal to or greater than the first frame rate.

摘要： An operating value of a first laser parameter of a laser device in a laser absorption spectrometer is optimized. The wavelength of laser device emitted light is adjusted by the first or a second laser parameter. The laser absorption spectrometer comprises a light intensity detector measuring the laser light intensity from the laser device. For each of multiple values of the first laser parameter: the light intensity detector measures light intensity obtained across a range of second laser parameter values, and an extremum in the light intensity measure and a peak position for the extremum are identified. A range of first laser parameter values is identified within the values of the first laser parameter for which there is a continuous trend in changes to the identified peak position with changes to the first laser parameter. The first laser parameter operating value is set to be within the identified range.

摘要： Detector data representative of an intensity of light that impinges on a detector after being emitted from a light source and passing through a gas over a path length can be analyzed using a first analysis method to obtain a first calculation of an analyte concentration in the volume of gas and a second analysis method to obtain a second calculation of the analyte concentration. The second calculation can be promoted as the analyte concentration upon determining that the analyte concentration is out of a first target range for the first analysis method.

摘要： A method and apparatus are described for detecting the presence and amount of elemental oxygen in a sample cell. The intensity of extreme ultraviolet light passing through the sample cell at a wavelength band overlapping at least one of the Schumann-Runge absorption lines of oxygen is detected and compared with a predetermined non-absorbed condition of the ultraviolet light. The non-absorbed condition may be achieved by narrowing the wavelength band such that the band does not overlap the Schumann-Runge absorption line, or may be achieved by detecting the ultraviolet light passing through a reference cell. Also described is a novel ultraviolet source in which a cold zone captures neutral atoms of the emission gas to reduce the affect of resonance absorption of emitted ultraviolet light by such neutral atoms.

摘要： Modulation-encoded light, using different spectral bin coded light components, can illuminate a stationary or moving (relative) target object or scene. Response signal processing can use information about the respective different time-varying modulation functions, to decode to recover information about a respective response parameter affected by the target object or scene. Electrical or optical modulation encoding can be used. LED-based spectroscopic analysis of a composition of a target (e.g., SpO2, glucose, etc.) can be performed; such can optionally include decoding of encoded optical modulation functions. Baffles or apertures or optics can be used, such as to constrain light provided by particular LEDs. Coded light illumination can be used with a focal plane array light imager receiving response light for inspecting a moving semiconductor or other target. Encoding can use orthogonal functions, such as an RGB illumination sequence, or a sequence of combinations of spectrally contiguous or non-contiguous colors.

摘要： A system and method to discriminate between a first preselected gas and at least one other preselected gas use of an absorption spectroscopy analyzer that includes a Herriott cell and a temperature sensitive light source. The light source operates at a temperature that emits a beam at a wavelength that corresponds to high absorption by a first preselected gas. When a predetermined level of this gas is detected in a gas sample, the analyzer changes the operating temperature of the light source to emit a beam at a wavelength that corresponds to high absorption by a second preselected gas. The second preselected gas can be a different isotope of the first preselected gas.

摘要： Methods and apparatuses (500) of generating and processing a real-time time-domain cavity ringdown spectroscopy (CRDS) signal from absorbing species m an optical detection system having an optical ringdown cavity (200) using off-axis paths (230) are provided. At least one modulated light signal (570) is generated using one or more light sources (520), each modulated at specified modulation frequency. Each modulated signal has harmonic frequency components and is input off-axis (230) relative to the cavity's optical axis (220). The cavity contains mirrors (210, 212, 214; 310; 410; 510, 512, 514) arranged in a predetermined configuration. The optical axis (220) is defined by a path passing through centers of mirrors (210, 212, 214; 310; 410; 510, 512, 514). The modulated light signal (570) is resonated off axis (230) without astigmatic optical. elements to produce CRDS signal and passes at least twice through cavity and across the mirrors (210, 212, 214; 310; 410; 510, 512, 814) without interfering, with itself. An overall path length through cavity is greater than path length of optical axis. A photodetector detects (550) the CROS signal, which is demodulated (560) dependent upon selected harmonics.
