Abstract: A method of determining a peak intensity in an optical spectrum is described. The method includes producing a two-dimensional array of spectrum values by imaging the optical spectrum onto a detector array. An offset using an actual location and an expected location of a peak of an interpolated subarray is used to adjust an expected location of another peak that is within another two-dimensional subarray. Interpolated spectrum values are then used to produce a peak intensity value of the second peak.

Abstract: In a spectrometry device, a control unit controls a light source so that input of excitation light to an internal space is maintained in a first period, and that the input of the excitation light to the internal space is stopped in a second period, and the analysis unit calculates the photoluminescence quantum yield of a long afterglow emission material on the basis of the number of absorbed photons of the long afterglow emission material obtained on the basis of excitation light spectral data in the first period and the number of light emission photons of the long afterglow emission material obtained on the basis of light emission spectral data in any of the first period, the second period, and a total period of the first period and the second period.

Abstract: A diagnostic testing method for a detector of a spectrometer. The spectrometer comprises a source of line spectra configured to emit at least one branched pair of spectral lines from an excited species. The method comprises performing a plurality of detector diagnostic measurements and diagnosing a detector operating condition. Each detector diagnostic measurement comprises measuring an intensity of a first spectral line emitted by an excited species of the source of line spectra using the detector, and measuring an intensity of a second spectral line emitted by the excited species of the source of line spectra using the detector. The first and second spectral lines emitted by the excited species of the source of line spectra form a branched pair of spectral lines, and the spectrometer is controlled to vary the intensity of the first and second spectral lines incident on the detector for the plurality of detector diagnostic measurements.

Abstract: A fluorescent single molecule emitter simultaneously transmits its identity, location, and cellular context through its emission patterns. A deep neural network (DNN) performs multiplexed single-molecule analysis to enable retrieving such information with high accuracy. The DNN can extract three-dimensional molecule location, orientation, and wavefront distortion with precision approaching the theoretical limit of information content of the image which will allow multiplexed measurements through the emission patterns of a single molecule.

Abstract: An optical manufacturing process sensing and status indication system is taught that is able to utilize optical emissions from a manufacturing process to infer the state of the process. In one case, it is able to use these optical emissions to distinguish thermal phenomena on two timescales and to perform feature extraction and classification so that nominal process conditions may be uniquely distinguished from off-nominal process conditions at a given instant in time or over a sequential series of instants in time occurring over the duration of the manufacturing process. In other case, it is able to utilize these optical emissions to derive corresponding spectra and identify features within those spectra so that nominal process conditions may be uniquely distinguished from off-nominal process conditions at a given instant in time or over a sequential series of instants in time occurring over the duration of the manufacturing process.
