Advanced Capabilities of the Multimodal Adaptive Optics Imager
We recently developed several versions of a multimodal adaptive optics (AO) retinal imager, which includes highresolution scanning laser ophthalmoscopy (SLO) and Fourier domain optical coherence tomography (FDOCT) imaging channels as well as an auxiliary wide-field line scanning ophthalmoscope (LSO). Some versions have also been equipped with a fluorescence channel and a retinal tracker. We des...
متن کاملAdaptive hyperspectral imager: design, modeling, and control
An adaptive, hyperspectral imager is presented. We propose a system with easily adaptable spectral resolution, adjustable acquisition time, and high spatial resolution which is independent of spectral resolution. The system yields the possibility to define a variety of acquisition schemes, and in particular near snapshot acquisitions that may be used to measure the spectral content of given or ...

متن کاملRetinal microscotomas revealed with adaptive-optics microflashes.
PURPOSE To develop a sensitive psychophysical test for detecting visual defects such as microscotomas. METHODS Frequency-of-seeing curves were measured with 0.75' and 7.5' spots. On each trial, from 0 to 4 stimuli were randomly presented at any of eight equally spaced loci 0.5 degrees from fixation. By correcting the aberrations of the eye, adaptive optics produced retinal images of the 0.75'...
متن کاملRetinal imaging using adaptive optics technology.
Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effect of wave front distortions. Retinal imaging using AO aims to compensate for higher order aberrations originating from the cornea and the lens by using deformable mirror. The main application of AO retinal imaging has been to assess photoreceptor cell density, spacing, and mosaic regular...
