A new image sensor technology for low light imaging can benefit the surveillance industry

A new image sensor technology enables unforeseen low light image quality. The technology has been developed at Pixpolar Oy in collaboration with Lappeenranta University of Technology (LUT) and promises better quality than other image sensor technologies on the market today.

Traditional image sensors produce such a poor image quality in low light conditions that any useful identification of objects or perpetrators is often impossible. For some time now, there has been a need to significantly improve image and identification quality.

Vladislav Marochkin, one of the two researchers behind the new technology, developed image sensor captures both visible light and Near Infra-Red light (NIR) that cannot be seen with the naked eye. The sensor comfortably operates in day light and darkness and cannot be disturbed by bright sources of light.

Marochkin, believes that the technology can be adapted to various industries, particularly automotive, aviation, maritime, and space.

"In principle it could also be used in the consumer digital cameras and smart phones" says Marochkin.

Cameras equipped with the developed black and white image sensor will extend almost two times the maximum detection range compared to existing technology. It will allow superior identification of persons and objects, and is immune to interference. It will allow an 80 percent reduction in NIR illumination cost or 60 percent reduction in the number of Security and Surveillance cameras required for the surveillance of a certain area.

"For example, some Security and Surveillance camera manufacturers attested that the developed image sensor excels in the physical characteristics of the light detection," says Marochkin.

The presented dissertation also improves performance and manufacturability of solid-state radiation detectors capable of detecting photons within low energy X-ray range, high energy X-ray and gamma-ray energy ranges, which would be beneficial for scientific and medical applications.

Vladislav Marochkin, Master of Science in Technology, will defend his doctoral dissertation in the field of technical physics at LUT on December 15th at 14:15, in the student union auditorium. His dissertation is titled Novel Solutions for Improving Solid-State Photon Detector Performance and Manufacturing. Professor Jyrki Räisänen of University of Helsinki will act as opponent. Professor Tuure Tuuva of LUT will act as custos.

The dissertation has been published in the Acta Universitatis Lappeenrantaensis research series number 720 of the university. ISBN 978-952-335-010-6, ISBN 978-952-335-011-3 (PDF), ISSN 1456-4491.
