This special section of JBO Volume 25, Issue 3, entitled “Biomedical Imaging and Sensing II,”
provides a collection of papers related to the topics of the conference “Biomedical Imaging andSensing Conference 2019” (BISC ‘19), which was held from April 24 to 26 in Yokohama, Japan.
This conference provides an international forum for reporting recent progress in imaging andsensing technologies in the fields of biology and medicine, as well as related areas.
In biomedical optics and photonics, optical tools are employed for the understanding andtreatment of diseases, from the cellular level to macroscopic applications. At the cellular level,
highly precise laser applications allow the manipulation, operation, or stimulation of cells, evenin living organisms or animals. Optical microscopy has been revolutionized by increased understanding of the different markers and their switching behavior. Marker-free microscopy technologies, like CARS (coherent anti-Stokes Raman scattering), SHG- (second-harmonic-generation) or
THG- (third-harmonic-generation) microscopy, optical coherence tomography (OCT), andDHM (digital holographic microscopy), are spreading into multiple biological and clinical imaging applications. OCT is continuously broadening its clinical applicability by becoming evenhigher resolution, higher speed, and more compact. In the broader field of optics and photonics,
biomedical imaging and sensing are the most quickly progressing and expanding areas.
Techniques developed in these areas could greatly advance physical, engineering, and biologicalknowledge, as well as optics and photonics technology.
This conference includes basic research at the cellular level through clinical applications ofvarious optical technologies. Topics covered include medical and biological imaging instrumentation and techniques, advanced microscopy, advanced endoscopy, super resolution, computational imaging, adaptive optics, structured illumination, OCT, digital holography, quantitative
phase imaging, diffuse spectroscopy and tomography, photoacoustic imaging, multimodal imaging and sensing, optical biopsy, multispectral imaging and sensing, spectroscopic imaging andsensing, scattering imaging, fluorescence imaging, molecular imaging, terahertz sensing, imaging
and sensing techniques for biomedicine, optical fibers and sensors for biomedicine, and multimodal optical diagnostic systems. Recently, computational imaging such as light field imaging, digitalholography, and compressive sensing is expected to open new imaging techniques to improveimage quality, obtain multimodal physical parameters, and apply the weak light condition usinga photon-counting device.
This special section includes interesting articles on OCT endoscopy, multimodal digital holographic imaging, computational fluorescence 3D imaging, and laser speckle contrast imaging for
medical applications. We believe that this special section on biomedical imaging and sensing willserve to advance biomedical imaging and sensing techniques.
