Abstract: The present disclosure provides a new visible light swept source that enables ultrafast visible light OCT to operate at a faster rate to reduce the motion artifacts and increase the field of view without sacrificing image quality. The new visible light swept source further provides for improved roll-off performance and mitigation of influence of RIN and wash-out effect for wide-field imaging. With a much-improved increase in imaging speed, increased signal-to-noise ratio (SNR), and increased imaging depth, visible light swept-source OCT (vis-ss-OCT) has the capability to perform more accurate functional and structural imaging.

Abstract: In an aspect, a method for additive manufacture of a three-dimensional object based on a computational model comprises steps of: grayscale photohardening a precursor material to form a portion of the object; and applying a hardened meniscus coating at a feature of the object; wherein the three-dimensional object is formed via at least the combination of the steps of gray scale photohardening and applying the meniscus coating. In some embodiments, the grayscale photohardening step is a grayscale photopolymerization step. In some embodiments, the applying a hardened meniscus coating step is a meniscus equilibrium post-curing step.

Abstract: A method of microscopy comprises collecting an emission light; symmetrically dispersing the collected emission light into a first order (“1st”) light and a negative first order (“−1st”) light using a grating; wherein the 1st light comprises spectral information and the −1st light comprises spectral information; capturing the 1st light and the −1st light using a camera, localizing the one or more light-emitting materials using localization information determined from both the first spectral image and the second spectral image; and determining spectral information from the one or more light-emitting materials using the first spectral image and/or the second spectral image; wherein the steps of localizing and obtaining are performed simultaneously. A spectrometer for a microscope comprises a dual-wedge prism (“DWP”) for receiving and spectrally dispersing a light beam, wherein the DWP comprises a first dispersive optical device and a second dispersive optical device adhered to each other.
