Hybrid Dispersion Laser Scanner
SCIENTIFIC REPORTS(2012)
摘要
Laser scanning technology is one of the most integral parts of today's scientific research, manufacturing, defense and biomedicine. In many applications, high-speed scanning capability is essential for scanning a large area in a short time and multi-dimensional sensing of moving objects and dynamical processes with fine temporal resolution. Unfortunately, conventional laser scanners are often too slow, resulting in limited precision and utility. Here we present a new type of laser scanner that offers ∼1,000 times higher scan rates than conventional state-of-the-art scanners. This method employs spatial dispersion of temporally stretched broadband optical pulses onto the target, enabling inertia-free laser scans at unprecedented scan rates of nearly 100 MHz at 800 nm. To show our scanner's broad utility, we use it to demonstrate unique and previously difficult-to-achieve capabilities in imaging, surface vibrometry and flow cytometry at a record 2D raster scan rate of more than 100 kHz with 27,000 resolvable points.
