摘要： An integrated spectrometer instrument, including an optical source formed on a chip, the optical source configured to generate an incident optical beam upon a sample to be measured. Collection optics formed on the chip are configured to receive a scattered optical beam from the sample, and filtering optics formed on the chip are configured to remove elastically scattered light from the scattered optical beam at a wavelength corresponding to the optical source. A tunable filter formed on the chip is configured to pass selected wavelengths of the scattered optical beam, and a photo detector device formed on the chip is configured to generate an output signal corresponding to the intensity of photons passed through the tunable filter.

摘要： An interferometer includes a resonant cavity having a movable mirror and at least one fiber optic component acting as a fixed mirror. A surface of the fiber optic component is coated with a reflective film. An actuator is coupled to the movable mirror, such that when a scattered optical beam is coupled to the cavity, interference occurs between the surface of the fiber optic component coated with reflective film and a surface of the movable mirror facing the surface of the fiber optic component coated with reflective film. The reflective film on the surface of the fiber optic component causes closely spaced spectral lines within the scattered optical beam to be suitably resolved.

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.
