 摘要：

 The recent decades have witnessed rapid development of various biomedical optical imaging methods. Compared with other biomedical imaging techniques, optical methods usually have the advantages of being harmless while providing high resolution and high sensitivity. The first part of my talk will focus on a paired-angle-rotation scanning (PARS) endoscopic probe for optical coherence tomography (OCT). OCT is based on a low-coherence interferometer and is able to obtain in vivo high-resolution images using coherent gate. The development of the forward-imaging PARS probe would be very helpful for many clinic applications. The second part of my talk will focus on array scanning based methods, including optofluidic microscopy (OFM) and wide-field microscopy (WFM). OFM is a low-cost on-chip microscope design based on aperture array scanning and can provide high-resolution microscopic image without the need of bulky and expensive objective lenses. WFM is based on a focus grid scanning scheme. As each focus is equivalent to an objective lens, we can equivalently have multiple objective lenses in the system, and thus expand the field-of-view. In comparison, conventional microscope only provides limited field-of-view, especially for high-magnification images.
