Lens-free Multi-Laser Spectral Light-Field Fusion Microsocpy

We present a device and method for performing lens-free spectral light-field fusion microscopy at sub-pixel resolutions while taking advantage of the large field-of-view capability. A collection of lasers at different wavelengths is used in pulsed mode and enables the capture of interferometric light-field encodings of a specimen placed near the detector. Numerically fusing the spectral complex light-fields obtained from the encodings produces an image of the specimen at higher resolution and signal-to-noise-ratio while suppressing various aberrations and artifacts.
