Multi-aperture hyperspectral imaging

Multi-aperture Fourier ptychographic microscopy, theory and validation

“…Multi-camera imaging systems are also attracting increasing interest in macroscopic imaging; for example, to super-resolve aliased images and to enable increased functionalities such as foveal imaging and multi-spectral imaging [37][38][39][40][41][42]. The essential motivation is to introduce and exploit diversity to increase the data bandwidth through parallelized image recording: in spatial sampling, in magnification and in spectral bandpass in the above examples.…”

Video-Rate Multispectral Imaging: Application to Microscopy and Macroscopy

“…Several techniques have been reported that solve the problem of snapshot recording of the threedimensional spectral data cube on a two-dimensional detector array using multiple apertures [5], reformatting [6,7] and inversion [8,9]. We have previously reported a snapshot multispectral imager of the reformatting type, called IRIS (image replicating imaging spectrometer), that provides very efficient use of detector pixels, very high optical throughput without rejection of light and hence very high signal-to-noise ratios [10].…”

In vivosimultaneous multispectral fluorescence imaging with spectral multiplexed volume holographic imaging system

“…Liquid crystal tunable filter 3 and acousto-optic tunable filter 4 have been used to increase the speed of spectral scanning. Therefore, some video-rate hyperspectral imaging technologies such as multiple apertures, 6 reformatting, 7 and inversion 8 have been considered. 5 In addition, the sequential acquisition mode is the intrinsic barrier that cannot be easily overcome.…”
