Clyde HyperSpectral Imaging and Technology Ltd., (ClydeHSI) is a management buy-out of the business, assets and good-will of CAMLIN Photonics Ltd., a wholly owned subsidiary of CAMLIN Ltd. We specialise in optical spectroscopy and hyperspectral imaging. With over 15 years direct experience in supplying spectral cameras and a wide range of hyperspectral systems for applications ranging from food quality to forensics, ClydeHSI is well suited to support our customers with cost effective, high performance instruments.
Hyperspectral imaging is a remote sensing, non-contact investigation that provides an optical spectrum at each and every pixel position of an image or in real-time on production line environment. The optical spectrum tells us what is at each point, it’s like a “fingerprint” of the material. The distribution of pixels with similar spectra demonstrates how the materials are distributed, and with appropriate calibration the signal levels can tell us the concentration of materials. Therefore, we know what is in an object, where it is, and how much is there. These are key parameters for product monitoring.
What is Hyperspectral Imaging?
During the last three decades, hyperspectral imaging (HSI) as developed into a smart analytical tool for a range of applications, for example in food and agricultural inspection.
The basic hyperspectral technique creates a spatial map of spectral features that enables identification of material components and their spatial distribution. Therefore, it can find objects, identify the distribution of materials, and detecting process values of performance.
As such HSI has become one of the key analytical tools for evaluating food products, their authentication, and security. The reason for this is that the spectral features are a “fingerprint” of the material and spectral imaging part demonstrates where that material is and with appropriate calibration the signal can be used to determine concentration of material. This has allowed HSI to be developed to be a fast, reliable technique, suitable for objective automated quality assessments.
Quality is not just about a single parameter, but is a combination of many parameters, especially in food assessment. It is here that optical spectroscopy and especially hyperspectral imaging has been very successful as it is non-destructive, non-contact, and can determine several parameters at the same time, and indeed can provide immediate responses.
Size, shape, colour, and surface texture of food can be easily measured by conventional machine vision systems. The prediction of other parameters such as fat, sugar, moisture content, protein, material homogeneity, or materials hazardous to the consumer for food safety, as well as packet seal integrity, can be made by hyperspectral imaging.
