Abstract
Custom fiber arrays can be used to encode 3-dimensional data for snapshot imaging techniques like imaging spectrometry or volumetric spectral domain OCT. This is achieved if array’s input is dense, while its output creates void spaces for spectral information. Here we present fiber arrays with entirely automatic development process based on 2-Photon Polymerization (2PP) additive manufacturing using Nanoscribe GmbH Quantum X system. Specifically, We developed two types of array prototypes: 10x10 to 1x100 and 20x20 - dense fiber spacing (1-2 microns fiber gap) to 20x20 – sparse fiber spacing (30-40 microns fiber gap). Fiber arrays were incorporated into prism-based imaging spectrometer system to demonstrate proof of concept spectral imaging experiments.
