Abstract: A compact spectrometer includes an excitation light source configured to generate excitation light and arranged to illuminate a spot on a sample. A dispersive element includes at least one movable component and spatially separates output light emanating from the sample in response to the excitation light into a plurality of different wavelength bands. A moveable component of the dispersive element causes the plurality of different wavelength bands of the output light to be scanned across a detector. The detector includes at least one light sensor that senses the wavelength bands of the output light and generates an output electrical signal in response to the sensed output light.

Abstract: Modular systems can be used for optical analysis, including in-situ analysis, of stimulated liquids. An excitation module can include a radiation sources, e.g., a laser, LED, lamp, etc. A detection module can include one or more detectors configured to receive spectral and/or temporal information from a stimulated liquid. Such systems can be used to identify or measure optical emissions including fluorescence or scattering. The efficient excitation of liquid samples and collection of emissions from the samples provides substantial, up to four-fold increase in the emission signal over prior systems. In an example, emission measurements can be conducted in an isolated sample compartment, such as using interchangeable modules for discrete sampling, flow-through sampling, or sampling via fiber probe. The systems and methods described herein can be used to characterize natural aquatic environments, including assessments of phytoplankton pigments, biomass, structure, physiology, organic matter, and oil pollution.

Abstract: A dual source system and method includes a high power laser used to determine elemental concentrations in a sample and a lower power device used to determine compounds present in the sample. A detector subsystem receives photons from the sample after laser energy from the high power laser strikes the sample and provides a first signal. The detector subsystem then receives photons from the sample after energy from the lower power device strikes the sample and provides a second signal. The high power laser is pulsed and the first signal is processed to determine elemental concentrations present in the sample. The lower power device is energized and the second signal is processed to determine compounds present in the signal. Based on the elemental concentrations and the compounds present, the compounds present in the sample are quantified.

Abstract: A method for measuring a spectrum of an optical sensor, advantageously in the infrared region, in which a light beam impinges on an optical sensor in contact with a medium to be measured, wherein the optical sensor transmits a measurement beam changed by the medium to be measured and the measurement beam is fed to a pyrodetector, which issues output signals corresponding to the spectrum. The intensity of the measurement signal is modulated before impinging on a pyrodetector. In order to provide a cost effective, vibration free measuring apparatus, which has a long lifetime, intensity modulation of measurement beam occurs by tuning-in wavelengths contained in the optical spectrum of measuring beam.
