Broadband blue light for optical coherence microscopy

Abstract

Optical coherence microscopy (OCM) is relatively new, noninvasive method of biomedical imaging. It uses Michelson interferometer to locate successive layers in tissue and enables reconstructing cross-sectional images that can be useful for medical diagnosis. In this work, we propose to develop new light sources for OCM to increase the resolution of images by introducing blue light. To achieve this goal, we decided to test a method known as achromatic second harmonic generation in our own, new configuration. © 2011 Photonics Society of Poland.
