Using high-tech laser gear, UN-backed team scans Ukraine historical sites to preserve them amid war

Under the plaintive painted eyes of the holy, a volunteer team of two United Nations-backed engineers watched as a whirling laser took a million measurements a second inside Kyiv's All Saints Church. The laser swept quickly across the church, part of the Kyiv-Pechersk Lavra, while taking a series of incredibly high-resolution photographs. “It's a critical moment," said Chiara Dezzi Bardeschi, who oversees Ukraine for UNESCO, the U.N.'s cultural agency.
