Home / Refractive Optical Flow Wavefront Modulator
Wavefront modulators are key components for adaptive optics (AO) systems, allowing dynamic correction of optical aberrations induced by the refractive index inhomogeneity of the imaging medium and/or the specimen, and the imperfections of an optical system. However, the complexity of adding a reflective wavefront modulator and a wavefront sensor into already complicated microscope has made AO prohibitive for its widespread. When the light propagates, the place where the phases are aligned at a certain time is said to be in. We present here the design and performance of a compact fluorescence microscope using a fully refractive optofluidic wavefront modulator, yielding imaging performance on par with that of conventional deformable mirrors, both in correction fidelity and articulation.
