Optical Imaging Procedures

Abstract

Diverse optical imaging procedures have been developed and applied successfully to biophotonics in research laboratories and clinical settings during the past several decades. Technologies that have contributed to these successes include advances in lasers and photodetectors, miniaturization of optical probes and their associated instrumentation, and development of high-speed signal processing techniques such as advanced computations in image reconstructions, computer vision and computer-aided diagnosis, machine learning, and 3-D visualizations. This chapter expands on the microscopic and spectroscopic technologies described in the previous two chapters by addressing photonics-based imaging procedures such as optical coherence tomography, miniaturized endoscopic processes, laser speckle imaging, optical coherence elastography, photoacoustic tomography, and hyperspectral imaging.
