Eye testing using speckle
text:
Laser speckle also known as eye testing using speckle can be employed as a method for conducting a very sensitive eye test. When a surface is illuminated by a laser beam and is viewed by an observer, a speckle pattern is formed on the retina. If the observer has perfect vision, the image of the surface is also formed on the retina, and movement of the head will result in the speckle pattern and the surface moving together so that the speckle pattern remains stationary with respect to the backgro
