Developing a Compact Instrument for UV

Until now, this technique was limited to visible and near-infrared wavelengths, and thus to a specific category of physical events. “Many phenomena that occur on very short time scales also take place on a very small spatial scale. To see them, you need to sense shorter wavelengths. Doing this in the UV or even X-ray ranges is a remarkable step toward this goal,” says Jinyang Liang, who led the study [Single‐Shot Ultraviolet Compressed Ultrafast Photography].

To record in this new range of wavelengths and to develop the technique into a user-friendly product, researchers designed a compact UV-CUP system with Christian‐Yves Côté of Axis Photonique Inc. via an academia-industry collaboration.

The new system features a patterned photocathode, which is used to simultaneously detect and encode “black light”. “Like a standard camera, our technology is passive. It does not produce light; it receives it. Therefore, our photocathode had to be sensitive to the photons emitted as UV light. This design makes our technique a stand-alone system that can be easily integrated into various experimental platforms,” says Jinyang Liang, who has been contributing to the development of CUP since his postdoctorate.

Liang worked with François Légaré, also an INRS professor, to generate and take images of UV pulses at the Advanced Laser Light Source (ALLS) laboratory.

The Institut national de la recherche scientifique (English: ‘National Institute of Scientific Research’) is the research-oriented constituent university of the Université du Québec system that offers only graduate studies. INRS conducts research in four broad sectors: water, earth and the environment; energy, materials and telecommunications; human, animal and environmental health; and urbanization, culture and society.
INRS has facilities in Quebec City, Montreal, Laval, and Varennes. The enabling legislation is An Act respecting educational institutions at the university level.
The Énergie, Matériaux et Télécommunications (EMT, Energy, Materials and Telecommunications) INRS-EMT is part of INRS.

INRS is a university dedicated exclusively to graduate level research and training. Since its creation in 1969, INRS has played an active role in Quebec’s economic, social, and cultural development and is ranked first for research intensity in Quebec and second in Canada. INRS is made up of four interdisciplinary research and training centres in Quebec City, Montreal, Laval, and Varennes, with expertise in strategic sectors: Eau Terre Environnement, Énergie Matériaux Télécommunications, Urbanisation Culture Société, and Armand-Frappier Santé Biotechnologie. The INRS community includes more than 1,400 students, postdoctoral fellows, faculty members, and staff.
