  • illumination microscopy
  • Although the term "structured illumination microscopy" was coined by others in later years, Guerra (1995) first published results in which light patterned by a 50 nm pitch grating illuminated a second grating of pitch 50 nm, with the gratings rotated with respect to each other by an angular amount to achieve magnification.

  • techniques
  • In point by point techniques (confocal, two-photon microscopy) the focusing of the excitation beam generally ensures that the maximum signal is collected when aberrations are minimal. (spiedigitallibrary.org)
  • Beginning in 1993, a number of improvements in the measurement techniques-notably using confocal microscopy, and then two-photon microscopy-to better define the measurement volume and reject background-greatly improved the signal-to-noise ratio and allowed single molecule sensitivity.

  • adaptive
  • We have developed adaptive optic devices for CLSMs using liquid crystals. (osapublishing.org)
  • The sources used for illuminating the adaptive optics loop are spectrally independent, in excitation and emission, from the sample, so they do not appear in the final image, and their use does not contribute to the sample bleaching. (spiedigitallibrary.org)
  • The classical implementation of an aberration correction system, initially developed for astronomy, is based on the use of an adaptive optics (AO) loop. (spiedigitallibrary.org)

(wikipedia.org)
  • Over the last 2 decades, adaptive optics for wavefront correction and beam shaping have been commonly used in laser facilities by means of a wavefront sensor that measures the spatial phase and a deformable mirror that corrects it. (wikipedia.org)
  • Adaptive Optics systems (AOs) are now a must have in ultra-high intensity facilities, with some of the most recent systems needing several AOs to function. (wikipedia.org)
  • Adaptive optics can correct these aberrations and considerably improve the contrast and resolution in different types of microscopy. (wikipedia.org)

  • Measurement
  • In addition, there has been a flurry of activity extending FCS in various ways, for instance to laser scanning and spinning-disk confocal microscopy (from a stationary, single point measurement), in using cross-correlation (FCCS) between two fluorescent channels instead of autocorrelation, and in using Förster Resonance Energy Transfer (FRET) instead of fluorescence. (wikipedia.org)
  • spherical
  • The typical value of 500-700 nm can be improved to 100-150 nm, which corresponds to an almost spherical focal spot with 5-7 times less volume than that of standard confocal microscopy. (wikipedia.org)
  • A lens that is focused onto the point source will have optics that change the spherical wave front into a planar wave before it passes through the pupil or aperture stop. (wikipedia.org)
  • samples
  • As emphasized by Booth, 1 the use of a S-H to measure distorted wave-fronts is not trivial in microscopy as it requires a point source emitter which is not naturally present in samples. (spiedigitallibrary.org)
