Hyper-Spectral Imaging and Advanced Imaging Solutions

Summary

Hyper-Spectral Imaging (HSI), also known as spectroscopic imaging, is a technique that integrates conventional imaging with spectroscopy to attain both spatial image and spectral information. This is like a 2D image but with every pixel providing detailed spectral information.  Hyper-spectral Imaging (HSI) technology has been around for more than 30 years and is deployed mainly in defence and satellite remote-sensing applications. In recent years, we have developed a cost-effective HSI sensors and solutions. This widens its use in commercial and industrial applications. Utilizing additional information in spectral domain, our HSI technologies also opened up new opportunities in tackling complex sensing scenarios and various video analytics applications.

Technology Benefits

Cost effective solution compared to existing HSI systems available in the market. This enables its wide deployment into new commercial/ industrial areasCompact and robust, suitable for outdoor deploymentAble to be customized to application requirementsEasy to adapt to customer existing imager (PolarFour can be designed as an optical add-on attachment to customer?s existing Imaging system)

Technology Application

This technology can be deployed for the following applications:Large area remote-sensing applications such as forestry/crops study, environment measurement, minerals detection and water quality monitoringMedical imaging and analysisRemote gas and chemical detectionSpectrum / Colour analysisForensic and spectral authenticity checkMachine visionQuality control of LED

Detailed Technology Description

We have two ready HSI technology solutions, with more innovation in the pipeline: Solution 1:An optical add-on to existing imaging camera and converting it into a HSI system.High spatial resolution (same resolution as the imaging camera).Scanning mode of operation.Providing High SNR based on direct light interference and Fast Fourier Transform to extract hyper-spectral information.Down to 5nm spectral resolution.Solution 2:Snap-shot capability. Able to acquire full hyper-spectral image in a single snap-shot.
