Graphenemight be the latest and corking hero of the scientific community , but lasers are still awesome and have a new prank up their arm to prove it . Researchers at the University of Hertfordshire in the United Kingdom have developed a twist that candetect the presence of airborne asbestos particles — a fireproof cloth now know to cause lung cancer like mesothelioma — using a optical maser - based detection organisation .
The previous and most accurate method for examination for asbestos involves filtering the air in a given location and send the captured speck to a lab for go - ray analysis and substantiation — a time consuming mental process . But this young attack takes advantage of the fact that asbestos is slimly charismatic , a rare property that ’s unequaled among fibrous material .
The detector first crucify a swarm of airborne particles with a laser and the crystalline structure of asbestos scatters the focussed light producing placeable patterns almost like a fingerprint . These atom are then sucked into the detector where they then pass through a magnetized arena . Since asbestos is also magnetic the particles align themselves and as they exit the demodulator the same optical maser - based light scattering technique is used to reassert their presence .
Working with colleagues in Spain the British squad has already developed prototypes that are currently undergoing field trials . And the researchers are affirmative that within 12 to 18 months the first production units will go on sale for around $ 800 . So here ’s to hop the field tests do go well , as this machine literally has the potential to pull through lives . [ OpticsInfoBaseviamedGadget ]
