An adaptive optics optical coherence tomography (AO-OCT) system with a non-modulated pyramid wavefront sensor (P-WFS) is presented. The P-WFS is implemented as add-on to a Shack Hartmann (SH) WFS based AO-OCT system, where the AO loop is driven by ei

An adaptive optics optical coherence tomography (AO-OCT) system with a 3-sided pyramid wavefront sensor (P-WFS) is presented. Compared to the Shack-Hartmann WFS, the P-WFS promises better sensitivity in low-light scenarios and greater flexibility in

Adaptive optics (AO) systems for retinal imaging have a small field of view (FoV) of 1°-2°. To increase the FoV we developed a multi-conjugated AO-system. By choosing different scanning patterns, aberrations introduced by the eye at different locat

Diffraction limited performance in an adaptive optics optical coherence tomography system is achieved by compensating for isoplanatic effects with a second deformable mirror within an area of ~4°×4° and for a 7 mm pupil diameter.

Using adaptive optics optical coherence tomography, human photoreceptors and retinal pigment epithelium (RPE) cells are typically visualized on a small field of view of ∼1° to 2°. In addition, volume averaging is required for visualizing the RPE

This paper presents an adaptation of the distributed-spline-based aberration reconstruction method for Shack–Hartmann (SH) slope measurements to extremely large-scale adaptive optics systems and the execution on graphics processing units (GPUs). Th

We propose an extension of the Spline based ABerration Reconstruction (SABRE) method to Shack-Hartmann (SH) intensity measurements, through small aberration approximations of the focal spot models. The original SABRE for SH slope measurements is rest

The central problem in Adaptive Optics feedback control is the reconstruction of the aberrated wavefront from wavefront sensor measurements. We recently presented a novel algorithm to compute the wavefront estimate directly from (Shack-)Hartmann inte

The distributed-spline-based aberration reconstruction (D-SABRE) method is proposed for distributed wavefront reconstruction with applications to large-scale adaptive optics systems. D-SABRE decomposes the wavefront sensor domain into any number of p

In a number of wasps, bees, and in particular ponerine ants, quantitative and qualitative variation in the profile of cuticular hydrocarbons is associated with variation in fecundity and is likely to serve for communicating the reproductive status of
