DESCRIPTION:Optical microscopy techniques can be greatly enhanced from sim
 ply imaging what you see in the focus of a microscope objective by structu
 ring the light that you use to illuminate the object.  The classic example
  of this is the confocal microscope where a point illumination is used wit
 h a point detector to reject light that comes from outside the focal plane
 .  That technique enables high-contrast\, three-dimensional imaging of an 
 object\, and can even achieve an improvement in resolution.  This talk cov
 ers a range of techniques\, some wide-field and some point scanning\, but 
 all loosely based on the confocal principle\, that can achieve or even bet
 ter the performance of the classic confocal microscope.  While the confoca
 l microscope most benefitted from the invention of the laser\, we show how
  it is developments in optical components\, detector technology and comput
 ational power that are enabling more recent developments\, and opening up 
 new possibilities for applications such as optical data storage.
