Looking Around Corners

cameraculture Femto-photography

Using short laser pulses and a fast detector, we built a device that can look around corners with no imaging device in the line of sight using scattered light and time resolved imaging.

Multi-depth Time-of-Flight Cameras

cameraculture Femto-photography

We repurpose a time-of-flight camera using coded illumination to recover time profiles of large-scale scenes and to acquire multiple depths per pixel.

Trillion Frames per Second Imaging

cameraculture Femto-photography

A camera fast enough to capture light pulses moving through objects.  We use ‘light in motion’ to understand reflectance, absorption and scattering properties of materials.
