Abstract: A rotary drive mechanism provides a mechanism for driving light dispersing element having a high wavelength-moving speed and a high wavelength-resolving power. The rotary drive mechanism includes a stepper motor as a rotary drive source; an update information setter for setting update information corresponding to the amount of change by which the motor should be rotated at a drive timing indicated by an input signal; a position information updater for holding position information which specifies the rotational position of the motor and for updating the position information based on the update information from the update information setter; a winding excitation state determiner for determining the amount or ratio of electric currents passed through the windings of the motor based on the updated position information provided from the position information updater; and a drive controller for controlling the electric currents based on a control signal from the winding excitation state determiner.

Abstract: Aspects of a tandem dispersive range monochromator and data knitting for the monochromator are described herein. In one embodiment, the monochromator includes a tandem diffraction grating, a grating drive motor that rotates the tandem diffraction grating to provide, by diffraction of broadband light, first dispersed wavelengths of light and second dispersed wavelengths of light, a detector that detects a first reflection from the first dispersed wavelengths of light and a second reflection from the second dispersed wavelengths of light, and processing circuitry that knits together data values from the first reflection and data values from the second reflection to provide a spectrum of combined data values. By using a tandem diffraction grating having different dispersive surfaces, measurements of relatively high precision and quality may be taken throughout a wider spectral range, and the measurements may be knitted together to provide a spectrum of combined data values.

Abstract: This invention discloses a laser induced breakdown spectroscopy (LIBS) apparatus based on a high repetition rate pulsed laser. The laser produces a train of laser pulses at a high repetition rate in the kHz or even higher range. When the laser beam hits the sample, it generates several thousands of micro-plasmas per second. Synchronized miniature CCD array optical spectrometer modules collect the LIBS signal from these micro-plasmas. By adjusting the integration time of the spectrometer to cover a plurality of periods of the laser pulse train, the spectrometer integrates the LIBS signal produced by this plurality of laser pulses. Hence the intensity of the obtained LIBS spectrum can be greatly improved to increase the signal-to-noise ratio (SNR) and lower the limit of detection (LOD). In addition, the influence of pulse to pulse variation of the laser is minimized since the obtained LIBS spectrum is the spectrum of a plurality of micro-plasmas produced by a plurality of laser pulses. The high repetition rate laser also makes it possible for fast scanning the laser beam over the sample surface such that an average spectrum of the sample is collected to overcome the sample non-uniformity issue or for performing spectral imaging of the sample by correlating the obtained LIBS spectrum with the position of the scanning laser beam.
Abstract translation: 本发明公开了一种基于高重复脉冲激光的激光诱导击穿光谱（LIBS）装置。 激光器在kHz或甚至更高的范围内以高重复率产生一串激光脉冲。 当激光束撞击样品时，它每秒产生数千个微等离子体。 同步微型CCD阵列光谱仪模块从这些微等离子体收集LIBS信号。 通过调整光谱仪的积分时间来覆盖激光脉冲串的多个周期，光谱仪将由多个激光脉冲产生的LIBS信号进行积分。 因此，可以大大提高所获得的LIBS频谱的强度，以增加信噪比（SNR）并降低检测极限（LOD）。 此外，由于获得的LIBS光谱是由多个激光脉冲产生的多个微等离子体的光谱，所以激光器的脉冲对脉冲变化的影响被最小化。 高重复率激光器还使得可以在样品表面上快速扫描激光束，使得采集样品的平均光谱以克服样品不均匀性问题或通过将获得的LIBS相关来进行样品的光谱成像 光谱与扫描激光束的位置。
