A system for structured illumination microscopy comprising: a light source for generating an excitation light beam ; a first micro lens array for splitting the excitation beam into an array of excitation foci ; a first lens aligned along the first axis and positioned one focal length away from a focal point of the first micro lens array , the first lens focusing the array of excitation foci ; a radial aperture block aligned along the first axis positioned at a front focal plane of the first lens , the radial aperture block being configured to block a plurality of low-angle central rays of the array of excitation foci , while allowing a plurality of high-angle, marginal rays of the array of excitation foci to pass through the radial aperture block , wherein the high-angle marginal rays are focused by the first lens along a high-angle and low-angle central rays are focused by the first lens along a low-angle; a galvanometric mirror aligned and positioned for redirecting and scanning the high-angle, marginal rays through an objective lens for focusing the redirected high-angle, marginal rays along a sample that generates an excitation by the sample and then the excitation from the sample is rescanned to generate patterned fluorescence emissions onto a second microlens array for locally contracting the patterned fluorescence emissions into a contracted pattern of fluorescence emissions , wherein the high-angle marginal rays evanescently excite the sample ; and a mirror arrangement for redirecting the contracted patterned fluorescence emissions onto a detector for detecting the patterned fluorescence emissions emitted by the sample . a light source for generating an excitation light beam ; a first micro lens array for splitting the excitation beam into an array of excitation foci ; a first lens aligned along the first axis and positioned one focal length away from a focal point of the first micro lens array , the first lens focusing the array of excitation foci ; a radial aperture block aligned along the first axis positioned at a front focal plane of the first lens , the radial aperture block being configured to block a plurality of low-angle central rays of the array of excitation foci , while allowing a plurality of high-angle, marginal rays of the array of excitation foci to pass through the radial aperture block , wherein the high-angle marginal rays are focused by the first lens along a high-angle and low-angle central rays are focused by the first lens along a low-angle; a galvanometric mirror aligned and positioned for redirecting and scanning the high-angle, marginal rays through an objective lens for focusing the redirected high-angle, marginal rays along a sample that generates an excitation by the sample and then the excitation from the sample is rescanned to generate patterned fluorescence emissions onto a second microlens array for locally contracting the patterned fluorescence emissions into a contracted pattern of fluorescence emissions , wherein the high-angle marginal rays evanescently excite the sample ; and a mirror arrangement for redirecting the contracted patterned fluorescence emissions onto a detector for detecting the patterned fluorescence emissions emitted by the sample . <EOS>
