Biomedical optical imaging is a rapidly evolving research area with numerous exciting applications in biological research and clinical diagnosis. For example, confocal and multiphoton microscopy provides cellular and subcellular spatial resolution for visualizing microscopic structures and functional mechanisms in biological systems. Optical coherence tomography greatly enhances the imaging depth and has led to successful applications in ophthalmology. Photoacoustic tomography combines optical contrasts and acoustic penetration depth elegantly. Diffuse optical tomography uses multiply scattered light to probe physiological states in large human organs. A variety of spectroscopic methods, such as fluorescence spectroscopy, Raman spectroscopy, and CARS, have been integrated into imaging systems for visualization of molecular makeup.

We invite investigators to contribute original research articles as well as review articles that showcase the recent advances in the field of biomedical optical imaging. We are particularly interested in articles describing novel designs and implementations of various biomedical optical imaging systems. Potential topics include, but are not limited to novel optical imaging system design, development, and evaluation with emphasis in:

• Microscopy
• Optical coherence tomography
• Diffuse optical tomography
• Photoacoustic tomography
• Multispectral imaging
• Approaches to break the resolution limits like STED and structured illumination
• Image reconstruction and image processing algorithms
