Microscopy Systems for Instant Internal Reflection Fluorescence/
Structured Illumination

    Description of Technology: Structured illumination microscopy (SIM) 
is a method that uses sharply patterned light and post-processing of 
images to enhance image resolution (in its linear form, doubling 
resolution). In traditional SIM, a series of images are acquired with a 
camera and computationally processed to improve resolution. This 
implementation of SIM has also been combined with total internal 
reflection fluorescence (TIRF), but the implementation still requires 
raw images relative to normal TIRF microscopy, thereby slowing 
acquisition 9-fold relative to conventional, diffraction-limited 
imaging. This TIRF/

[[Page 60711]]

SIM system includes a radial aperture block positioned at a plane 
conjugate to the back focal plane of the objective lens, thus allowing 
only high-angle marginal annular light beams from a laser source to 
excite the sample. The radial aperture block can be replaced with a 
digital micromirror device for varying the evanescent wave to allow 
nanometric localization of features in the axial direction. A spatial 
light modulator (SLM) can be used to alter the phase of the excitation 
to optimally induce evanescent, patterned excitation at the sample. 
Various embodiments of the TIRF/SIM system allows for high-speed, 
super-resolution microscopy at very high signal-to-noise (SNR) ratios 
for biological applications within ~200 nm (e.g., the evanescent wave 
decay length) distance of a coverslip surface.
    Potential Commercial Applications:  High speed microscopy.
    Competitive Advantages:  Low cost of manufacture.
    Development Stage:  Prototype.
    Inventors: Hari Shroff (NIBIB), Justin Taraska (NHBLI), John
