Summary
This study introduces a virtual reflected-light microscopy (VRLM) system for creating realistic 3D digital models of specimens. The VRLM system accurately captures both shape and reflectance, enhancing digital microscopy for online viewing.
Area of Science:
- Digital Microscopy

Purpose of the Study:
- To develop a virtual reflected-light microscopy (VRLM) system.
- To enable accurate 3D shape and reflectance estimation from specimen images.
- To create interactive digital representations for online dissemination.
Main Methods:
- A VRLM system was developed using a microscope, digital camera, motorized stage, and software.
- The system estimates both shape and reflectance from multiple specimen images.
- Anaglyph creation was used to generate depth information and illumination cues.
Main Results:

01:05Total Internal Reflection Fluorescence Microscopy
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
01:37Super-resolution Fluorescence Microscopy
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 developed.
01:16Confocal Fluorescence Microscopy
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,...
