#Using Lasers To Save Earth's Cultural Monuments History is unwritten by the destruction of great artifacts.
Preserving modern wonders for posterity is the main inititiative of Cyark a nonprofit that uses 3-D laser scanning to create a digital archive of the world s cultural heritage sites.
Key to Cyark is a portable eye-safe laser scanner made by Cyark founder Ben Kacyra.
The scanner is a LIDAR system which is like radar except instead of bouncing back radio waves it uses lasers.
LIDAR systems existed before Cyark but they were used mainly in labs where someone would bring an object
and get it scanned. Parts of the music video for Radiohead's House of cards were recorded this way.
This picosecond timer gives the laser scans accuracy down to a millimeter. With the technology already made it took a tremendous act of destruction to inspire its use in historical preservation.

The more photonics components go into a system, the cheaper they have to be in order for the system to be affordable,
