Low Cost Adaptive Optics

Building a low cost adaptive optics system of moderate performance is not difficult in principle, and in this article one approach adopted by our group is described. Our system is based on a membrane mirror, a Shack-Hartmann sensor and a simple control system. Two breadboard AO systems are described and we speculate on some possible future developments.

Computerized Adaptive Student Help: Experiments in Low-Cost Artificially Intelligent Automation of Student-Tutor Interaction

The lessons attained from research in artificially intelligent learning systems demonstrate the complexity in their attempts to learn either broad categories of knowledge or explicit tasks and skills that require extensive use of resources. This paper describes an investigation into some energy effective and lowcost approaches to developing lightweight artificially intelligent learning systems ...

Low-Cost Tunable Adaptive Optics

The tunable acoustic gradient index (TAG) lens is capable of producing rapidly tunable complex optical beams and patterns from a single source beam. The lens uses piezoelectric transducers to modify the density and refractive index within a fluid to generate lensing behavior. The type of beam that the lens generates depends on the electrical driving signal applied to the piezoelectric transduce...

Low-cost Flexible Speed Control Experiments

A set of experiments on speed control realised with LEGO elements is presented. Despite their simplicity and low cost, the setups allow to address several interesting control problems. To witness this statement, part of the activity for the course titled ‘Engineering and Technology of Control Systems’ is described. The characteristics of the proposed experiments make them very suitable both for...

FPGA technology for high speed, low cost adaptive optics

The Durham University Centre for Advanced Instrumentation (formerly the Astronomical Instrumentation Group) has been involved in the development of both research and facility class astronomical adaptive optics systems and their associated control systems for over 20 years. The centre also has interests in commercial and non-astronomical research AO systems, including the areas of novel wavefron...
