Abstract: A fluorescence hyperspectral microscopy system featuring structured illumination and parallel recording includes a light projection sub-system, a detection sub-system, and an electrical controller. The light projection sub-system includes a digital light processing (DLP) module for generating linear excitation light, a first lens set, an optical path allocation element, and an objective lens. The detection sub-system includes a second lens set, a frequency-dividing reflection element, a two-dimensional light detector, and a light collection element. With the detection sub-system performing detection in conjunction with the light projection sub-system, and the electrical controller controlling the DLP module, a two-dimensional moving platform, and the two-dimensional light detector, the fluorescence hyperspectral microscopy system provides increased resolution and can obtain accurate information in spatial and spectral dimensions and hence a four-dimensional hyperspectral image of the object under detection.

Abstract: An electronic device may be provided with a color sensing ambient light sensor. The color sensing ambient light sensor may measure the color of ambient light. Control circuitry in the electronic device may use information from the color sensing ambient light sensor in adjusting a display in the electronic device or taking other action. The color sensing ambient light sensor may have light detectors with different spectral responses. A test system may be used to calibrate the color sensing light sensor. 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.

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-plasma emissions per second. Synchronized miniature CCD array optical spectrometer modules collect the LIBS signal from these micro-plasma emissions. 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-plasma emissions produced by a plurality of laser pulses. The high repetition rate laser also makes it possible to measure the LIBS signal at a short and a long integration time and mathematically combining the two spectra to obtain a LIBS spectrum with enhanced dynamic range.

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排放。 同步微型CCD阵列光谱仪模块从这些微等离子体发射中收集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发射的光谱，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短和长的积分时间测量LIBS信号并且数学地组合两个光谱以获得具有增强的动态范围的LIBS光谱。
