Laboratory of Applied Computational Imaging

Research at LACI centres on the implementation of laser modulation techniques in new optical imaging devices.

Current work is focused on the following three areas:

• Compressed ultrafast photography (CUP)
• High-precision laser beam shaping
• Photoacoustic tomography (PAT)

LACI is equipped with a wide array of equipment:

The Laboratory of Applied Computational Imaging is available to Centre Énergie Matériaux Télécommunications Research Centre faculty, students, and staff for their research projects, with the lab manager’s authorization.

Lab resources can also be used for external collaborations or research and development contracts.

The Laboratory of Applied Computational Imaging is used for ultrafast imaging, photoacoustic microscopy, wavefront engineering, and high-precision laser beam shaping. It has paved the way for a number of developments, including:

• High-speed real-time 3D profilometry
• Single-shot high-speed imaging of dynamic events in biomedicine
• Single-shot ultrafast imaging of dynamics events in physics
• Fast characterization of the optical properties (e.g., lifetimes and absorption) of materials

LACI receives financial support from the Canada Foundation for Innovation (CFI), the Government of Quebec, the Natural Sciences and Engineering Research Council of Canada (NSERC), and Fonds de recherche du Quebec (FRQ).
