A fast handheld two-photon fiber-optic fluorescence endoscope for three-dimensional (3D) in vivo cellular imaging is developed. The compact handheld probe of the two-photon endoscope can simply be placed into contact with the target tissue to reveal clear 3D surface and subsurface histological images without biopsy. The new system has, to the best of our knowledge, the largest field of view (FOV) of 475 μm × 475 μm and a 3D imaging volume larger than 475 μm × 475 μm × 250 μm. A real-time two-photon fluorescence image is displayed at 0.4 mm2/s. The lateral and axial resolutions of the two-photon fluorescence endoscope are better than 1 and 14.5 μm, respectively.
