Microscopes are an important tool in biomedical research as it allows for detailed observation and imaging of tissues. Since biological materials are opaque by their nature, severe light scattering ...

Researchers invented a new type of microscope called reflective matrix microscope, which uses adaptive optics techniques. Non-invasive microscopic techniques such as optical coherence microscopy and ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

Optical instruments are how we see the world, from corrective eyewear to medical endoscopes to cell phone cameras to orbiting telescopes. This course extends what you have learned about first-order, ...
