“…Spherical surface lens models can only match the first-order properties of the eye and do a poor job in matching aberration content or off-axis properties of the real eye [ 17 ]. Aspheric eye models are much better suited to illustrating clinical levels of longitudinal aberrations, both on- and off-axis.…”

“…These models are usually designed in such a way it is easy to add and control aberrations. For example, Yamaguchi et al [ 78 ] used a phase plate for that purpose, while [ 24 ] used a tunable crystalline lens, and Letfullin et al [ 17 ] and Galetskiĭ et al [ 21 ] used biomorph mirrors to reproduce aberrations and their temporal dynamics in real time. More minimalistic models have also been used, such as by Shen et al [ 34 ] or Guerra et al [ 59 ].…”

“…For example, refs. [ 9 , 24 , 78 ] used aberrating plates to statically reproduce aberrations, while [ 17 , 21 ] used flexible biomorph mirrors to dynamically reproduce aberrations. Other models might use spatial and phase light modulators (SLM) to control the amount of incident light and add aberration.…”

The purpose of this review is to aggregate technical information on existent optomechanical eye models (OME) described in the literature, for image quality assessment in different applications. Several physical eye models have been reviewed from peer-reviewed papers and patent applications. A typical eye model includes an artificial cornea, an intraocular lens or other lens to simulate the crystalline lens, an aperture as the pupil, and a posterior retinal surface, which may be connected to a light sensor. The interior of the eye model may be filled with a fluid to better emulate physiological conditions. The main focus of this review is the materials and physical characteristics used and the dimensional aspects of the main components including lenses, apertures, chambers, imaging sensors and filling medium. Various devices are described with their applications and technical details, which are systematically tabulated highlighting their main characteristics and applications. The models presented are detailed and discussed individually, and the features of different models are compared when applicable, highlighting strengths and limitations. In the end there is a brief discussion about the potential use of artificial eye models for industrial applications.

Deformable mirror resolution-matching-based two-stage wavefront sensorless adaptive optics method

et al. 2020

View full text Add to dashboard Cite

In high-power laser facilities, the application of a traditional wavefront control method is limited under the influence of a continuous phase plate (CPP). In order to obtain a satisfactory far-field intensity distribution at the target of the beamline with the CPP, a novel deformable mirror (DM) resolution-matching-based two-stage wavefront sensorless adaptive optics method is proposed and demonstrated. The principles of the DM resolution-matching method and two-stage wavefront sensorless adaptive optics method are introduced, respectively. Based on the numerical model, the matching relationship between the actuator space of the DM and the spatial period of the CPP is investigated. By using the resolution-matched DM, the feasibility of the two-stage wavefront sensorless adaptive optics method is numerically and experimentally verified. Both the numerical and the experimental results show that the presented DM resolution-matching-based two-stage wavefront sensorless adaptive optics method could achieve the target focal spot control under the influence of the CPP, and the profile and the intensity uniformity of the corrected focal spot are optimized close to the designed ideal focal spot.
