A new type of light sensor may enable medical and security imaging via low cost cameras, according to new research. The research was recently published in Nature’s Scientific Reports.

The team of researchers, from the University of Surrey, developed a new multispectral light sensor that detects the full light spectrum, from ultra-violet (UV) rays to visible and nearly infrared light.

Near infrared light is useful for performing certain non-invasive medical procedures, including measuring oxygen level in tissue and detecting tumors. This type of light is also frequently used in security camera systems as well as for quality control in the agriculture and food industry.

According to researchers, having a low cost near infrared system, as well as conventional imaging, is a gateway to several new possibilities.

Dr. Richard Curry, lead researcher, from the University of Surrey’s Advanced Technology Institute, said in a statement, “Until now specialist light sensors have been limited in the kinds of light they can detect, with multiple sensors required to measure different ranges of the light spectrum, significantly increasing cost.”

Curry explained, “This new technology could allow surgeons to ‘see’ inside tissue to find tumors prior to surgery as well as equip consumer products, such as cameras and mobile phones, with night imaging options. This is useful for capturing quality pictures in the dark, and may eventually enable parents to simply monitor a child’s blood or tissue oxygenation level via a smartphone camera which could be linked to healthcare professionals.”

The sensors are highly flexible and are able to be produced cheaply, using the same laser printers that are found in homes and offices. As opposed to other sensors, this one does not require specialized manufacturing conditions.
