Imaging Biological Samples with Optical Microscopy01:18

Imaging Biological Samples with Optical Microscopy

4.7K
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.

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

13.2K
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,...

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

2.7K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Overview of Microscopy Techniques

10.3K
The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Area of Science:

  • Microscopy and imaging science
  • Optical engineering
  • Biomedical optics

Background:

  • Advanced 3D microscopy techniques like light-sheet fluorescence microscopy (LSFM) are crucial for biological research.
  • Optical aberrations limit imaging performance, especially beyond superficial cell layers, necessitating adaptive optics (AO).
  • Traditional LSFM systems require separate aberration correction for illumination and detection paths, increasing complexity.

Approach:

  • This study investigates the application of AO in an oblique plane microscope (OPM), a simplified LSFM variant.
  • A single deformable mirror was employed to simultaneously correct aberrations in both the illumination and fluorescence detection paths of the OPM.
  • A projection imaging mode was utilized to stabilize and enhance wavefront correction in a sensorless AO configuration.

Key Points:

  • Implementing AO in OPM reduces system complexity compared to conventional LSFM.
  • AO in OPM successfully restores the alignment between the light-sheet and focal plane.
  • Sensorless AO in OPM, using a projection imaging mode, improves wavefront correction stability and efficacy.

Conclusions:

  • Adaptive optics integrated into an oblique plane microscope significantly enhances 3D imaging capabilities.
  • The study demonstrates diffraction-limited resolution and a twofold improvement in signal strength in zebrafish embryo imaging.
  • This AO-OPM system offers a more streamlined and effective approach for high-resolution in vivo and in vitro biological imaging.
