This webinar will provide an overview of the state of the art in hyperspectral imaging, discussing the major architectures for hyperspectral imagers together with their performance trade-offs. Specifically, presenter Hod Finkelstein, Ph.D, Chief Technology Officer of TruTag Technologies, will describe a recent implementation of an autonomous, high-resolution, cost-efficient hyperspectral camera.
Development of a Hand-Held High Resolution Hyperspectral Imaging Camera
By Hod Finkelstein, Ph.D. MBA and Alexandre Fong, M.Sc., MBA
A technical overview of the development of HinaLea Imaging’s Fabry-Pérot interferometer (FPI) based proprietary hyperspectral imaging technology is presented. This technology, which was originally developed to read the company’s optically-encoded particles, has been adapted to create the first high performance front staring true hyperspectral imaging camera in a handheld, self-contained, ultra-compact form factor.
Hyperspectral Imaging Microscopy in Pathology
By Alexandre Fong M.Sc, MBA, Mark Hsu, Ph.D. and Mersina Simanski, BSEE
The introduction of fluorescence microscopy technique has added the ability to examine cell condition and function in addition to structure in research and clinical diagnosis methods such as immunochemistry. However, interpretation of these images is often subjective due to limitations in human vision to distinguish subtle color differences particularly due to spatially overlapping emissions. Hyperspectral imaging data-cubes when combined with image processing techniques such as spectral unmixing and classification, enables such features (i.e. distinguishing tumor margins) to be easily visualized and identified.
Hyperspectral Imaging Cameras in Rapid Detection and Potential Diagnosis of Agricultural Crop Threats
By Alexandre Fong, Director, Hyperspectral Imaging, HinaLea Imaging and Mark Hsu, Director of Product Development
Remote monitoring of crops via satellites using color cameras was the earliest form of spectral imaging in agricultural management. Due to limited capabilities, only basic plant health parameters could be reported. The advent of hyperspectral imaging systems has presented the industry with the potential ability to not only monitor plant health, but also to detect potential plant pathogens. A new, dynamically adjustable and cost effective hyperspectral imaging technology is introduced as a tool for early identification and prevention of spread of such diseases to mitigate crop losses.
Award-Winning High Resolution Spectral Imaging Camera
HinaLea’s Model 4100H is an award-winning hyperspectral imaging camera with a built-in illumination source. It is recognized as the world’s first high-resolution, handheld, autonomous hyperspectral camera and that was awarded the SPIE Best Camera and Imager Prism Award in 2017. The Model 4100H is compact, lightweight and designed for field and factory use. It captures a high-resolution snap-shot image of an object, with spectra at each pixel for the visible (400 – 1000 nm) wavelength range in up to 550 bands. It features a color touch screen interface, battery operation and embedded object identification. It is ideal for medical imaging, precision agriculture, industrial machine vision and food and other quality inspection applications.
