Roadmap on nonlinear optics–focus on Chinese research
JPhys Photonics, 2023 In nonlinear optical systems, the optical superposition principle breaks down. The system’s response (including electric polarization, current density, etc) is not proportional to the stimulus it receives. Over the past half century, nonlinear optics has

Monocular Real Time Full Resolution Depth Estimation Arrangement with a Tunable Lens
Applied Sciences, 2022 This work introduces a real-time full-resolution depth estimation device, which allows integral displays to be fed with a real-time light-field. The core principle of the technique is a high-speed focal stack acquisition method combined with an efficient

New Journal of Physics, 2004 The establishment of ultrafast optics as an important research field followed the invention of the laser in the late 1950s. However although the generation of ultrashort optical pulses was observed not long after the laser was first invented, it is only in the last few years that ultracompact lasers have been devised which generate picosecond or sub ...

Through-focus scanning optical microscopy [PDF]
SPIE Proceedings, 2011 Through-focus scanning optical microscopy (TSOM) is another 'scanning' based method that provides threedimensional information (i.e. the size, shape and location) about micro- and nanometer-scale structures. TSOM, based on a conventional optical microscope, achieves this by acquiring and analyzing a set of optical images collected at various focus ...
