报告摘要:The concept of spectral imaging is very simple: by recording an image in multiple spectral bands it is possible to extract additional information from subtle variations in spectral signatures that are invisible in conventional images. The fundamental problems associated with the implementation and exploitation of spectral imaging are: how to record the three-dimensional data cube (two transverse dimensions and wavelength) in ‘real-time’ using a conventional two-dimensional detector and how to invert the recorded data to extract useful and reliable information. I will describe novel optical techniques that uniquely enable recording of the spectral data cube in a single snapshot, which can be inverted using physical models for light propagation in complex structures to yield quantitative chemical images. Real-world applications range from in vivo biophotonic imaging of oxygen consumption in biomedical research and ophthalmology to thermal infrared imaging of gas spectra.

报告摘要:The imaging systems of the late 20th century would have been easily recognised and understood by the early pioneers of imaging systems three hundred years earlier. But recent years have witnessed increasing introduction of electronics and computational systems enabling a progressive transfer of the image-formation function from traditional optical systems to hybrid optical-digital imaging. Fusing techniques inspired by RADAR, x-ray imaging and communications theory; computational imaging includes computer recovery of images as an integral component of imaging-system design and implementation to yield imaging systems with unprecedented functionality. Using computational imaging it is now possible for the first time to image with both high resolution over extended depth ranges; for the performance of $100 computational-imaging microscope to equal a $100,000 microscope or to record 3D images in a single snapshot. This talk will describe the application development and application of new computational imaging in fields ranging from surveillance systems to microscopy.
