A complete solution for imaging or beam-shaping applications
The Wavefront Sensorless AO Demonstrator (WS-AOD) provides a platform for utilizing metric-based wavefront control with BMC MEMS deformable mirror (DM) technology. While conventional AO systems perform closed-loop DM control using direct measurements of the wavefront as feedback, the metric-based approach uses details in the aberrated light to improve clarity. The system is configured to use a hill climbing algorithm to compensate for wavefront phase errors.
By utilizing the included algorithm to manipulate the mirror surface, the mirror compensates for aberrations and converges to an optimal profile. The user has access to the open source code to balance correction capability between maximum signal and minimal time. The system is intended to serve three main purposes:
1) Serve as an introduction to wavefront sensorless adaptive optics principles. By operating the system in its current form, the user is able to understand the details involved in properly implementing a metric-based adaptive optics solution on an optical system.
2) Implement the Demonstrator as a stand-alone aberration compensator. The operator can use this system on its own to correct for aberrations inserted into the optical path. By introducing aberrations in the sample stage, the system can be optimized for a multitude of use cases from laser research applications to scanning laser microscopy.
3) Enable integration of the components into an existing optical system. The user can easily integrate the hardware into an existing optical system and utilize the open source software code for metric-based correction.
