General wave optics propagation scaling law

A Wave Optics Propagation Code for Multi-Conjugate Adaptive Optics

We describe the purpose and sample results of a wave optics propagation simulation developed to study multi-conjugate adaptive optics for 4-10 m class telescopes. This code was developed to assess the impact of di raction e ects and a variety of implementation error sources upon the performance of the Gemini-South MCAO system. These e ects include: Hartmann sensing with extended and elongated l...

Scaling law for computational imaging using spherical optics.

The resolution of a camera system determines the fidelity of visual features in captured images. Higher resolution implies greater fidelity and, thus, greater accuracy when performing automated vision tasks, such as object detection, recognition, and tracking. However, the resolution of any camera is fundamentally limited by geometric aberrations. In the past, it has generally been accepted tha...

Rapid calculation of paraxial wave propagation for cylindrically symmetric optics.

When calculating the focusing properties of cylindrically symmetric focusing optics, numerical wave propagation calculations can be carried out using the quasi-discrete Hankel transform (QDHT). We describe here an implementation of the QDHT where a partial transform matrix can be stored to speed up repeated wave propagations over specified distances, with reduced computational memory requiremen...
