• pinhole
  • Fluorescence emission gathered from the specimen is filtered through a confocal pinhole aperture to reject light that originates from regions removed from the focal plane. (zeiss.com)
  • A confocal interferometry system for making interferometric measurements of an object, the system including an array of pinholes positioned to receive a source beam and, for each pinhole in the array of pinholes, separate the source beam into a corresponding reference beam on one side of the array of.

  • biology
  • Refinements in design have simplified confocal microscopy to the extent that it has become a standard research tool in cell biology. (microscopyu.com)
  • The development of microscopy revolutionized biology, gave rise to the field of histology and so remains an essential technique in the life and physical sciences. (wikipedia.org)
  • image
  • The purpose of using coefficients is to characterize the degree of overlap between images, usually two channels in a multidimensional microscopy image recorded at different emission wavelengths. (wikipedia.org)
  • subcellular
  • Today, more and more researchers are interested in linking macroscopic properties and behavior - such as memory learning - with microscopy at the single cell and subcellular level, as well as studying molecular events such as gene control and neuronal activity like excitatory and inhibitory signaling.

  • Methods
  • It often involves a biopsy for subsequent laboratory analysis with various methods that include visual microscopy . (photonics.com)
  • Up to now, most frequently used methods to quantify colocalization calculate the statistical correlation of pixel intensities in two distinct microscopy channels. (wikipedia.org)
  • images
  • Linear lobe deconvolution as well as nonlinear restoration of 4Pi confocal raw data with their point-spread functions (PSF's) leads to almost-identical images, irrespective of whether the 4Pi confocal PSF relies on constructive or destructive interference. (osapublishing.org)
  • 2. The confocal interferometry system of claim 1 further comprising a second imaging system that images the array of pinholes onto the array of detector elements. (google.com.au)
  • Good optical sectioning, often referred to as good depth or z resolution, is popular in modern microscopy as it allows the three-dimensional reconstruction of a sample from images captured at different focal planes. (wikipedia.org)
  • light
  • 5. The confocal interferometry system of claim 4 , wherein the first imaging system further comprises a refracting surface positioned between the object and the beam splitter to receive light rays from the object. (google.com.au)
  • Confocal microscopy uses a scanning point or points of light to illuminate the sample. (wikipedia.org)
  • point
