Microwave Photonic Radars: What can Photonics bring to Radars?
题目:Microwave Photonic Radars: What can Photonics bring to Radars?
时间:2024-07-01
地点:电院1-518A会议室
As the only method for all-weather and long-distance target detection and recognition, radar has been intensively studied since it was proposed, and is considered as an essential sensor for future intelligent society. In the past few decades, great efforts have been devoted to improving radar’s functionality, precision, and response time, of which the key is to generate, control, and process a wideband signal at a high speed. Thanks to the high frequency, large bandwidth, low loss transmission, and electromagnetic immunity provided by modern photonics, implementation of the radars in the optical domain can provide better performance in terms of resolution, coverage, and speed which may not be achievable using traditional, even state-of-the-art electronics. In this talk, I'll give an overview of the photonic technologies that are currently known to be attractive for radars. System architectures and their performance that may interest the radar society are emphasized. Emerging technologies in this area and possible future research directions are discussed.详情>>

Computational fiber imaging using digital holography and deep learning
题目:Computational fiber imaging using digital holography and deep learning
时间:2024-06-24
地点:电院群楼1号楼418A
Light has the potential to recognize the development of diseases, to prevent them or to heal them early and gently. Traditionally, however, lens-based imaging results in bulky systems. We outline the 3D imaging with needle-sized, lensless multicore fiber endoscopes using holography. Deep learning is promising for label-free cancer
diagnostics in neurosurgery using minimally invasive endoscopy. Besides biomedicine, data transmission with fiber networks will be highlighted. Multimode fibers show promise for improving data rates in optical communications but come with the challenge of compensating for scattering effects. Physics-informed deep learning
enables to correct the scattering, resulting in advancing security and data rate. Fiber imaging promises advances in various fields such as information, biomedicine and environmental protection.详情>>
