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

Abstract

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.
