Super-resolution in microscopy and optical recording. The classical resolution limit imposes severe restrictions on the performance of optical instruments, especially in optical microscopy and optical recording. Improved understanding of the fundamental principles involved in super-resolution should allow substantial increases in resolution to be achieved. We aim to explore theoretically and experimentally the performance of different super-resolution schemes alone and in combination, including ....Super-resolution in microscopy and optical recording. The classical resolution limit imposes severe restrictions on the performance of optical instruments, especially in optical microscopy and optical recording. Improved understanding of the fundamental principles involved in super-resolution should allow substantial increases in resolution to be achieved. We aim to explore theoretically and experimentally the performance of different super-resolution schemes alone and in combination, including optical masks, near-field optics, detector arrays, multi-photon imaging and digital deconvolution. Selected methods will be demonstrated with practical examples in multi-photon microscopy. Applications in super-high density optical recording will also be studied.Read moreRead less

The laser sources generally do not have simple (Gaussian) distributions. The applicant has recently developed a model, describing free propagation of complex (non-Gaussian) laser beams. This project seeks to develop a comprehending model for laser beams propagation through complex optical systems. The effects of various optical elements will be defined employing a novel method known as SAFE (Stable Aggregate of Flexible Elements) which is a compromise between geometrical and physical optics. Applying this model to micromachining and optical data storage (ODS), which need high beam quality (low divergence and good focussibility), enable accurate predictive capability critical to the optimisation of micromachining and ODS designs.Read moreRead less
