Abstract:
By measuring 4D spatial-angular distributions at high speed, light-field imaging can obtain high-dimensional dynamic information with an accurate imaging model. However, there are a series of technical limitations for current light-field methods, including the tradeoff between spatial and angular resolutions, different kind of reconstruction artefacts, substantial computational costs and optical aberrations, which greatly limit its performance in practical applications. Here in this talk, I will first give a brief introduction of current light-field imaging methods, and then talk about our recent advancements in addressing these limitations for broad applications in microscopy. Finally, I will show how we apply light-field microscopy to solving biological questions and the remaining challenges.
