The University of Michigan- Shanghai Jiao Tong University Joint Institute (UM-SJTU JI) stands at the forefront of technological innovation with its unique academic atmosphere and advanced scientific explore. JI boasts a strong research team which keeps innovating and strives to produce results that will lead the industry and ultimately benefit the human beings.
In order to help the public discover the mystery of scientific research, JI has launched a series of mini-workshop to introduce faculty’s research.

In the past few years, due to potential applications in personal medical and telemedicine, compact microscopy has become a research hotspot. This imaging technology is thought to cut costs associated with telemedicine, eliminate the need for professional and technical personnel to analyze imaging and provide fast, inexpensive medical diagnostics in resource-constrained areas. The core of this technology is to remove the lens. In the compact micro-imaging technology, digital coaxial holography can achieve lensless imaging and reconstruction of the sample image by recording a single holographic image.
At a recent mini-workshop, Professor Jigang Wu introduced the research work of his experimental team on compact microscopy, including a lensless coaxial holographic microscope using Taber illumination and iterative reconstruction algorithm and two methods to improve the resolution of the image, i.e., pixel super resolution method and interpolation method. Numerical simulations and experimental results show that submicron resolution microscopy can be achieved with this compact lensless microscopy system.
Dr. Jigang Wu joined JI as an assistant professor and doctoral adviser in 2011. He has been engaged in biomedical imaging and bio-photonics research, including wide-field-of-view microscope imaging technology, optical coherence tomography and digital coaxial holography technology. He has published 25 academic papers in domestic and foreign academic journals, has 11 authorized domestic and US patents, and has served as a peer reviewer of a number of relevant international journals.
