  • Highly compact multi-optical-junction optical flowcell and flexibly deployable optical sensing assemblies and systems for in-situ real-time spectroscopic measurements
    Patent number: 8859990
    Abstract: A highly compact multi-optical-junction optical flowcell includes a housing having an internal channel, to which a plurality of source optical signal modules can be coupled, e.g., in a peripheral manner. The source optical signal modules can include a set of LEDs and/or semiconductor lasers, and can be coupled to the flowcell by way of a standard optical coupling such as an SMA-type optical connector. An excitation detection apparatus or subsystem can also be coupled to the flowcell to facilitate multiple types of optical measurements, including fluorescence spectroscopy, absorption spectroscopy, and turbidity measurements. A sensing apparatus or system that includes a multi-optical-junction optical flowcell, a plurality of source optical signal modules, and an excitation detection apparatus can be carried by or deployed on a wide variety of platforms, such as Autonomous Underwater Vehicles (AUVs), Autonomous Surface Vehicles (ASVs), buoys, or other platforms, in a space efficient and power efficient manner.
