Arbitrary multi-site two-photon excitation in four dimensions

Daria, Vincent Ricardo; Stricker, Christian; Bowman, Richard; Redman, Stephen; Bachor, Hans


We demonstrate dynamic and arbitrary multisite two-photon excitation in three dimensions using the holographic projection method. Rapid response (fourth dimension) is achieved through high-speed noniterative calculation of the hologram using a video graphics accelerator board. We verify that the projected asymmetric spot configurations have sufficient spatiotemporal photon density for localized two-photon excitation. This system is a significant advance and can be applied to time-resolved...[Show more]
