TLDR
Using an indoor closed-loop configuration optical system, it is demonstrated that the residual error after open-loop correction could be smaller than 0.08lambda (RMS: root mean square value) if the initial wavefront aberration is below 2.5lambda.Abstract:
Used as a wavefront corrector, a liquid crystal spatial modulator (LC-SLM) has good repeatability and linearity, which are essential for open-loop adaptive optics, and the open-loop optical system can increase the light energy efficiency by a factor of two for the LC-SLM and improve the system bandwidth. In order to test the performance of the LC-SLM in open-loop correction, an indoor closed-loop configuration optical system is constructed on the open-loop control method. With this method, it is demonstrated that the residual error after open-loop correction could be smaller than 0.08lambda (RMS: root mean square value) if the initial wavefront aberration is below 2.5lambda (RMS), and the repeatability error of open-loop correction is smaller than 0.01lambda (RMS).read more

Two-photon polymerization with optimized spatial light modulator
TL;DR: In this article, a correction procedure for the nonlinear process of the two-photon polymerization (TPP) was developed and specifically characterized, where a simple interferometric method was used to determine the surface distortion of the SLM, calculated a correcting hologram and confirmed the correction with the polymerization of test structures.

The possibility of compensating astronomical seeing
TL;DR: In this article, the effect of a number of turbulent elements leads to an unsteady enlargement of the image, perhaps with some irregular shifting in position, and the seriousness of this is evident when one realizes that ideally the 200-inch Hale telescope is capable of giving diffraction images of stars about %0 oi a second of arc in diameter, yet the size of the "seeing image" produced is in the range j4 second to perhaps 5 or 10 seconds, being about 2 seconds in diameter on the average.

TL;DR: In this article, the focus is changed back to angular resolution and collecting power of a telescope by setting the diffraction limit of the telescope, which is determined by its diameter, rather than its angular resolution.
