Reduction of spherical-aberration impact in microscopy by wavefront coding.
In modern high-NA optical scanning instruments, like scanning microscopes, the refractive-index mismatch between the sample and the immersion medium introduces a significant amount of spherical aberration when imaging deep inside the specimen, spreading out the impulse response. Since such aberration depends on the focalization depth, it is not possible to achieve a static global compensation f...
متن کاملWavefront-aberration sorting and correction for a dual-deformable-mirror adaptive-optics system.
Many next-generation adaptive optics (AO) systems for vision will have two deformable mirrors (DMs) instead of one: a high-stroke, low-resolution mirror (the woofer) and a low-stroke, high-resolution mirror (the tweeter). We developed a zonal wavefront-control algorithm and validated it using simulations. Rather than separating the woofer and tweeter corrections into two independent control pro...
متن کاملAutomated spherical aberration correction in scanning confocal microscopy.
Mismatch between the refractive indexes of immersion media and glass coverslips introduces spherical aberrations in microscopes especially for high numerical aperture objectives. This contribution demonstrates an automated adjustment of the coverslip correction collar in scanning confocal microscopy to compensate for spherical aberrations due to coverslip thickness mismatch. With a motorized co...

متن کاملComparing the extended depth-of-field imaging performance of spherical aberration and asymmetric wavefront coding
We compare the image quality between asymmetric wavefront codings and the simpleto-manufacture spherical aberration over an extended focal range. We verify and explain the superior performance of the spherical aberration via simulation results. c © 2009 Optical Society of America OCIS codes: (060.2320) Fiber optics amplifiers and oscillators; (060.4510) Optical communications
