Structured Illumination Microscopy is a method in which a fluorescent sample is illuminated with a number of patterns containing high spatial frequencies. This encodes super-resolution information into the classical light microscopy image which is the successively recovered by Fourier-space based reconstruction methods.
This talk will introduce into the topic and then highlight some of the concepts behind StructuredIlluminationMicroscopy.jl, which supports some of the fastest algorithms for reconstructing images measured by structured illumination. The package features Fourier-space reconstruction approaches including upsampling, reconstruction and noise-reduction steps. It exploits rFFTs and SeparableFunctions.jl, wherever possible, minimizes the memory footprint by working on pre-allocated arrays and fully supports GPU acceleration via CUDA.jl.
I am heading a department at the Leibniz Institute of Photonic Technology, where our research focuses on imaging cellular function at high resolution. We develop new light microscopy techniques to measure multidimensional information in small biological objects such as cells, cellular organelles or other small structures of interest.
Computer-based reconstruction methods, in particular in Julia, are a core focus and support many of our developments.
