摘要： An auto-aligning system is presented. One embodiment of the auto-aligning system includes a launcher unit configured to direct a first laser beam and a second laser beam through a chamber, wherein the first laser beam is co-linear with the second laser beam. The auto-aligning spectroscopy system further includes a receiver unit configured to receive the first laser beam and the second laser beam passing through the chamber. The receiver unit includes a first detector configured to determine an intensity of the first laser beam. The receiver unit also includes a second detector configured to determine a deviation of the second laser beam from a determined position. Further, the auto-aligning spectroscopy system includes a motorized stage configured to align the launcher unit to a base-line position based on the determined deviation of the second laser beam.

摘要： A method of Raman detection for a portable, integrated spectrometer instrument includes directing Raman scattered photons by a sample to an avalanche photodiode (APD), the APD configured to generate an output signal responsive to the intensity of the Raman scattered photons incident thereon. The output signal of the APD is amplified and passed through a discriminator so as to reject at least one or more of amplifier noise and dark noise. A number of discrete output pulses within a set operational range of the discriminator is counted so as to determine a number of photons detected by the APD.
