Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

12.2K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Confocal Fluorescence Microscopy

15.9K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Imaging Biological Samples with Optical Microscopy

9.1K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

    Area of Science:

    • Computational imaging
    • Optical microscopy
    • Biomedical engineering

    Background:

    • Light field microscopy (LFM) offers high-speed 3-D volumetric imaging.
    • Current LFM reconstruction shows non-uniform spatial resolution across depth.
    • This limitation hinders detailed volumetric analysis, especially in the center of the imaged volume.

    Purpose of the Study:

    • To enhance the spatial resolution uniformity of light field microscopy.
    • To address the depth-dependent resolution limitations of LFM.
    • To improve volumetric imaging performance for biological applications.

    Main Methods:

    • Implemented wavefront coding using phase masks in the LFM optical path.
    • Developed an extended optical model for the wavefront-coded LFM.
    • Utilized a Fisher information-based metric to optimize phase mask parameters.
    • Validated the approach with simulations and experimental measurements using a USAF 1951 target.

    Main Results:

    • Wavefront coding with phase masks significantly improved resolution uniformity across depth.
    • Using two phase masks provided superior control over LFM performance.
    • Demonstrated successful in vivo volumetric calcium imaging in larval zebrafish brains.

    Conclusions:

    • Wavefront coding is an effective strategy to overcome resolution limitations in LFM.
    • The developed method enables more accurate and uniform 3-D reconstructions.
    • This advancement holds promise for high-resolution in vivo biological imaging.
