Hyperspectral Imaging
LIghtHaus has a new technology in hyperspectral imaging. The invention reduces the cost of such imaging cameras by many times as compared to existing hyperspectral cameras. In addition, LightHaus's hyperspectral camera is one of the most compact hyperspectral camera systems in the world. With such cost reduction, LightHaus can now help many cost-sensitive industries for applications such as:

Manufacture and industrial monitoring


HS imaging is well-known for a wide variety of industrial applications such as material inspection or quality control. It is actively deployed as automated vision for the paper, textile, pharmaceutical, color printing, semiconductor and waste/recycling industries. For example, textile manu¬facturers can evaluate color uniformity or inspect color patterns during the manufacturing process. Similarly, cosmetics, food, printing, building materials and numerous other products can be monitored during production.


Food quality control and safety:


HS imaging can be used to monitor the critical steps and processes in food manufacturing in order to ensure quality consistency. HS camera has also proven to be useful in early and non-visible detection of molds and fungi in food supply. Poultry processing plants also have demands for such imaging in order to perform rapid detection of contamination from fecal matter and other toxins.


Agricultural Crop Monitoring:


HS imaging has been used for monitoring the development and health of crops. In Australia, farmers are using HS imaging to detect grape variety and develop an early warning system for disease outbreaks. There is also ongoing effort to detect the chemical composition of plants which can be used to detect the nutrient and water status of wheat in irrigated systems.


Art monitoring and security


>HS imaging can reveal the "DNA" of an art-work beyond what our eye can see. Art piracy can trick the eye but not a HS camera. This is because HS imaging is able to measure the detailed light spectrum reflected from each point of an art-piece. This makes perfect art duplication almost impossible.


Forensic applications:


HS imaging has helped forensic scientists in terms of noninvasive analysis of crime scenes, evidence, or other objects of interest. It can help to pan a crime scene for spectral evidence while maintaining spatial information. In addition, it has been shown to be an useful tool for detection of counterfeit notes, forged documents and other altered documents in law enforcement.


Medical imaging:


HS imaging can provide early detection and measurement of necrotic and ischemic tissue to assist in examining and treating wounds. Research also shows that HS imaging help to give a better understanding of gene activity and protein expression in the early detection of ovarian cancer.


Chemical, bio-agent and pollutant sensing :


HS camera has been proven effectively to determine the presence of a suspect pollutant in a drainage system and also the detection of toxins and bio-organisms in the water supply. Another area of interest is the use of HS sensing for bio-defense to detect biological agents, chemical weapons that have been maliciously introduced into a populated area.




Many minerals can be identified from HS images, and their relation to the presence of valuable minerals such as gold and diamonds is well understood. There is a current constant on-going effort to understand detect oil and gas leakages from pipelines and natural wells using HS imaging.


Search and Rescue Mission


Surveillance using HS imaging has been shown to be useful in search and rescue mission especially since natural vegetation has distinctly different spectral signatures compared to man-made object.


Depending on customer requirements, LightHaus will provide a complete solution to deploy hyperspectral imaging techniques to automate the inspection of their processes, and develop image processing algorithms tailored to increase their productivity.
