Laser Sensing Display

An interactive laser-based projection system capable of sensing touch at a distance without the use of external cameras.

Damping-Driven Time Reversal for Waves

[collaboration with the ESPCI – Ecole Superieure de Physique Chimie de Paris] We present a counterintuitive method to create a time-reversed wave by applying a time-controlled dissipation pulse. By successive application of this principle, we can destroy a monochromatic component of a broad band wave to make an “in situ” spectral hole burning. We demonstrate… Continue reading Damping-Driven Time Reversal for Waves
