What kind of information can phase-contrast microscopy reveal that is not visible with a bright-field microscope?
What kind of information can phase-contrast microscopy reveal that is not visible with a bright-field microscope?
Phase-contrast microscopy can reveal many cellular structures that are invisible with a bright-field microscope.
Explain the principle of phase-contrast microscopy.
Explain the principle of phase-contrast microscopy.
Phase-contrast microscopy is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations.
Why are phase shifts invisible without special arrangements?
Why are phase shifts invisible without special arrangements?
Without special arrangements, phase changes are invisible because photographic equipment and the human eye are only sensitive to amplitude variations.
What causes changes in amplitude (brightness) in phase-contrast microscopy?
