THIRD TYPE OF COVID-19 TEST DEVICE
PHOTONICS BASED TEST
To diagnose and contain the spread of coronavirus, testing is critical. There are two types of Covid-19 tests — those that are designed to detect whether you have the infection now, or those crafted to check whether you have been previously infected by the virus — SARS-CoV-2 — that causes the disease. Like any other product these tests have varying degrees of accuracy and reliability, and can be used to achieve different aims.
We want technologies that are fast, accurate, have high capacity, that don't require expensive, complex laboratory equipment or the expertise of highly trained people, but there's nothing which fills all of those criteria at the moment, says Professor Jon Deeks, a biostatistician and testing expert at the University of Birmingham, UK.
‘We haven't got any perfect test like that, but there are some which are sort of good in some aspects, but not in others.’

A New Type of Test that fulfils all of Professor Jon Deeks of University of Birmingham is our PHOTONICS BASED TEST
What is Photonics
Photonics is the science and technology of generating, controlling, and detecting photons, which are particles of light. Photonics underpins technologies of daily life from smartphones to laptops to the Internet to medical instruments to lighting technology. The 21st century will depend as much on photonics as the 20th century depended on electronics. This page will contain links and resources to let you learn about photonics and understand its impact on the world.
Photonics is the science of light. It is the technology of generating, controlling, and detecting light waves and photons, which are particles of light. The characteristics of the waves and photons can be used to explore the universe, cure diseases, and even to solve crimes. Scientists have been studying light for hundreds of years. The colors of the rainbow are only a small part of the entire light wave range, called the electromagnetic spectrum. Photonics explores a wider variety of wavelengths, from gamma rays to radio, including X-rays, UV and infrared light.
It was only in the 17th century that Sir Isaac Newton showed that white light is made of different colors of light. At the beginning of the 20th century, Max Planck and later Albert Einstein proposed that light was a wave as well as a particle, which was a very controversial theory at the time. How can light be two completely different things at the same time? Experimentation later confirmed this duality in the nature of light. The word Photonics appeared around 1960, when the laser was invented by Theodore Maiman.
