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.

Authentication and Detection of Forgeries in Artwork

George Shu, Ph.D. and Alexandre Fong M.Sc.

According to the Fine Arts Experts Institute (FAEI), as much as half of the works in the roughly $60 billion art market are forgeries. Although the authentication process relies mostly on the visual skills of art experts who scrutinize pieces based on style and technique, more scientific technology-based methods are growing in demand and importance as part of the verification process. Hyperspectral imaging provides a convenient and economical means to enhance and possibly obviate such costly and sometimes destructive means.

Accurate Spectral and Chromaticity Measurement of Consumer Electronic Displays

Authored by: Alexandre Fong M.Sc., MBA and Mark Hsu, Ph.D.

The rapid improvements in the performance of display technology has resulted in the need for better metrology tools to ensure accurate rendering of color and uniformity. Hyperspectral imaging offers a solution that combines the advantages of the ability imaging colorimeters to capture entire areas in a single measurement with the accuracy of a spectroradiometer.


Measuring Aging and Water Content in Meat Products

In addition to spatial information which can be useful for size sorting and other machine vision tasks, by identifying distinctions in images which are not only invisible to the eye but also to color (RGB) cameras and even multi-spectral imagers, hyperspectral imaging cameras can provide rapid assessment of product quality metrics such as moisture, aging, protein and fat content, marbling and more.


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.
