Theoretical designs based on wavefront aberrations were created to simulate a toric monofocal and a toric bifocal intraocular lens.
We seek unbiased methods for estimating the target vergence required to maximize visual acuity based on wavefront aberration measurements.
Second, the AOPT loop incorporates the wavefront sensor, the deformable mirror, the pupil tracker and the control algorithm based on wavefront sensing.
A wavefront corrector (reflective or refractive) is a must in such an auxiliary system where the algorithm that controls the wavefront reshaping process can be based on wavefront sensor measurements or any other relevant parameter such as image quality [ 1].
In this case, the performance of the AOPT loop, i.e., the correction based on wavefront sensing, was below the average, due probably to a wrong wavefront sensor measurement at the beginning of the iterations.
Except for the spikes, the AOPTL loop correction was comparable to the AOPT loop, i.e., the correction done based on wavefront sensing, demonstrating that pupil tracking can be used as an active optical element in wavefront correction.
This loop provides the classical adaptive optics correction in real time based on wavefront sensing while pupil tracking is also active without any contribution to the correction.
Figure 10 shows the basic schematics of the loop configuration by which pupil tracking is aimed to enhance the correction done based on wavefront sensing.
After the control algorithms were programmed in both C++ and Labview, the adaptive optics of the imaging system comprised of five elements, the deformable mirror, the wavefront sensor, the control algorithm based on wavefront sensing, the pupil tracker and finally the control algorithm based on pupil tracking.
For high resolution AO control, whether the DM commands are based on slope data or based on wavefront phase estimate from slope measurements, it is critical to reduce the errors arising from the edge effects.
