A new publication from Opto-Electronic Advances discusses diffraction-limited visible imaging for large aperture telescopes. The deformable mirror used in adaptive optics can change its surface to ...

Synthetic aperture imaging has enabled breakthrough observations from radar to astronomy. However, optical implementation remains challenging due to stringent wavefield synchronization requirements ...

OAM detection of vortex beams using #-type lines is presented. In the far-field distribution of #-type line diffraction, the primary diffraction spots associated with the OAM of the beam can be easily ...

Fundamental diffraction physics says that a larger aperture improves both resolution and penetration. However, aperture size has historically been limited by system complexity and unknown benefit in ...

ISAMFP concept and system overview. (a) Schematics of beam-scanning, aperture-scanning, and ISA acquisition. (b) Optical layout of the system. (c) Target motion trajectories with recorded frames. (d) ...

Place the laser on top of the lab jacks, making sure the laser is pointed away from people. Place the slide mount on the optical rail and insert the sample slide to the slide mount. Plug in the laser ...
