Abstract

Imaging fiber bundle is a necessary element in a conventional endomicroscopy imaging system. The combination of a proximal spatial light modulator as a means of achieving beam scanning and an imaging fiber bundle for light delivery and collection enables the wavefront at the distal end of the fiber bundle to be synthesized, controlled and scanned. In this way the endomicroscope is very different from conventional systems which use proximal scanning mirrors or distal scanning heads. Thus, it is necessary to investigate the effect of primary parameters, such as diameter of each core, core-core separation and phase mask applied to the face of the imaging fiber bundle on the characteristics of focusing spot. These effects were simulated by numerically generating distal wavefronts and propagating them using the method of angular spectrum of plane-wave. The axial and lateral resolution and SNR were introduced to evaluate the characteristics of the focus. The imaging system could be optimized and reduced constraints on the imaging fiber bundle used based on these results.
