Instantaneous non-diffracting light sheets

An optical measurement device comprising:

• an illumination source;
• an objective lens;
• a line-projection system configured to simultaneously illuminate a pupil plane associated with the objective lens with a static distribution of a plurality of 1D coherent beams including illumination from the illumination source, wherein each of the 1D coherent beams of the plurality of 1D coherent beams extends lengthwise along a coherent direction between boundaries of the pupil plane, have a width along an incoherent direction perpendicular to the coherent direction, and are distributed in a parallel distribution along the incoherent direction, wherein each of the 1D coherent beams of the plurality of 1D coherent beams is spatially coherent along the coherent direction and spatially incoherent along the incoherent direction;
• an objective lens configured to form a light sheet in an imaging plane based on an incoherent superposition of the plurality of 1D coherent beams, wherein the light sheet extends along an optical axis of the objective lens and along a direction corresponding to the incoherent direction, wherein the light sheet has a thickness along a direction corresponding to the coherent direction;
• a sample stage configured to secure a sample in the imaging plane;
• a collection objective lens configured to capture light from the sample in response to the light sheet;
• and
• a detector configured to generate an image of the sample based on the light from the collection objective lens.
