Three-Dimensional Printing of Nonlinear Optical Lenses

Three-dimensional nonlinear optical endoscopy.

The development of miniaturized nonlinear optical microscopy or endoscopy is essential to complement the current imaging modalities for diagnosis and monitoring of cancers. We report on a nonlinear optical endoscope based on a double-clad photonic crystal fiber and a two-dimensional (2-D) microelectromechanical system mirror, enabling the three-dimensional (3-D) nonlinear optical imaging throug...

diffraction-unlimited three-dimensional optical nanoscopy with opposing lenses

The resolution of far-field optical microscopy stagnated for a century, but a quest began in the 1990s leading to nanoscale imaging of transparent fluorescent objects in three dimensions. Important elements in this pursuit were the synthesis of the aperture of two opposing lenses and the modulation or switching of the fluorescence of adjacent markers. The first element provided nearly isotropic...

In-lab three-dimensional printing

The development of the microscope in 1590 by Zacharias Janssenby and Hans Lippershey gave the world a new way of visualizing details of morphogenesis and development. More recent improvements in this technology including confocal microscopy, scanning electron microscopy (SEM) and optical projection tomography (OPT) have enhanced the quality of the resultant image. These technologies also allow ...
