Holographic microscopy has emerged as a tool for in situ imaging of microscopic organisms and other particles in the marine environment. It is appealing due to the relatively large undisturbed sampling volume and simplified optical configuration compared to other imaging systems.
Researchers at Florida Atlantic University have developed a novel in situ, submersible holographic imaging system for particle and plankton characterization. The system consists of a computer controlled, high-resolution digital camera and nanosecond pulsed laser. It can be operated in a lens-less configuration or with a microscope objective and is capable of viewing particles ranging from 10 μm - 3.5 cm in size. Sample volume can be varied from ~1 - 100 mL depending on the configuration.
FAU is seeking partners to advance this technology into the marketplace through licensing or development partnerships.
Digital Holography for Real-Time Non-Invasive Monitoring of Larval Fish at Power Plant Intakes
The early stages of the fish life cycle are critical for survival into the reproductive stage. Without appropriate larval densities and live feed densities, the survival of the fish are at risk. Larval enumeration and growth monitoring systems allow aquaculture producers to both optimize hatchery space and to maintain proper densities of live feed organisms. Current methods of enumeration and growth monitoring are manual methods requiring significant resources and suffer from inaccuracy.
Researchers at FAU have developed a cost-effective tool for reliable larval enumeration and continuous growth monitoring in a non-intrusive manner. The system is comprised of an image capture front end which utilizes a light field rendering camera and strobe light. The image is then processed using a proprietary algorithm to enhance the image and then analyzed. This technology could potentially reduce feed costs, improve survivability, and lower production costs of aquaculture.

Current underwater imaging faces challenges with low visibility and high noise, limiting the detection of hazardous objects like Explosive Ordinance Devices (EOD). This problem necessitates a technology capable of penetrating these barriers to provide clear, actionable imagery.
Researchers at Florida Atlantic University have developed a compact, active imaging system that surmounts these challenges, fitting into small unmanned underwater vehicles (UUV) and enhancing image quality through advanced noise-reduction techniques. Its unique illumination method and high dynamic range imaging redefine underwater clarity, outperforming existing solutions in compactness and image fidelity.
