Researchers at Tel Aviv University (TAU) have been working on a hyperspectral sensor that can detect more than 1,000 colors to monitor and analyze contaminants to soil and water. Prof. Eyal Ben-Dor of TAU’s Department of Geography and the Human Environment says that reading this extensive spectrum of color allows the sensor to analyze 300 times more information than the human brain can process.
The HSR sensor interprets reflected sunlight radiation with each color representing a different chemical reaction between compounds. The sensor has recently been used to identify contaminated areas around oil and gas pipelines, water in marinas, and agricultural areas impacted by salt in the soil.
The use of the HSR camera allows for real-time analysis, as opposed to the traditional method of sending samples off to a lab for analysis. The sensor can read information as close as 0.4 inches and as far as 500 miles away, giving it an incredible range for placement on the ground to satellites.
