The Laboratory of Applied Computational Imaging (LACI) enables research into the development of new optical imaging techniques and devices for physics and biomedicine. The LACI specializes in the development of new optical instruments for applications in biology, physics, and materials science. The lab is equipped with advanced instruments that support research in ultrafast optical imaging, high-precision beam shaping, and photoacoustic microscopy.
Compressed ultrafast photography (CUP)
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)
- (1) Single-wavelength 200-mW continuous-wave lasers at 471 nm, 532 nm, 589 nm, and 671 nm.
- High-power continuous-wave infrared laser with wavelengths tunable from 700 nm to 1000 nm
- High-repetition-rate nanosecond pulsed lasers at 532 nm and 559 nm
- High-repetition-rate dye laser with wavelengths tunable from 602 nm to 660 nm
- Scientific CMOS camera (2048x2048 pixels, 100 fps)
- Electron-multiplying CCD camera (1024x1024, 20 fps)
- High-speed interface CCD cameras (1280x860, 2000 fps)
- High-speed colour camera (1280x1024, 606 fps)
- UV/X-ray streak camera (4096x4096, 500 Gfps)
- Visible streak camera (2048x2048, 100 Gfps)
- Upright microscopy (with 4x, 10x, 20x, and 40x objective lenses)
- 0.7" Digital micromirror devices (1024x768, 20 kfps)
- 0.45" Digital micromirror devices (1140x912, 6.6 kfps)
- Visible electro-optic modulator (bandwidth: 100 MHz)
- Acousto-optic modulator (spectral range: 400–450 nm, bandwidth: 50 MHz)
Current services available:
- Characterization of 3D surfaces ($80 per sample*)
- Wide-field microscopy ($15 per hour*)
- Characterization of phosphorescence lifetimes ($120 per sample*)
- Characterization of fluorescence lifetimes ($150 per sample*)
- Characterization of absorption properties ($120 per sample*)
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
