Sample text

Geometric optics uses linear rays to represent the paths traveled by light. Pinhole Imaging The simplest imagi ng device is a pinhole ape rture. Here's a simple experiment. Make a pinhole near the center of a large sheet of alum in um foil, light a candle, and extinguish all other illumination in the room. Hold a sheet of plai n white or, better, waxed paper about 2 ft from the candle, and place the pinhole midway between the paper and the candle. Observe an inverted image of the candle flame on the paper (Fig 2-1).

At best, a filter might reduce the transmission of white light to a color range (bandwidth ) of 5 nm at the expense of most of the white light's energy. For medical purposes, the color of light can be used to enhance absorption or transmission by a target tissue with a certain absorption spectrum. The wavelength specificity of a laser greatly exceeds the absorption specificity of pigments in tiss ues. In addition, monochromatic light is not affected by chromatic aberration in lens systems. Thus, monochromatic light can be focused to a smaller spot than can white light.

An object has an infinite number of point Fi gur e 2·' Pinhole imaging . (Illustration developed by Edmond H. Thall, MD, and Kevin M. Miller, MD, and rendered by C. H. ) 27 28 • Clinical Optics sources, and each point sou rce is infinitesimall y small. Light radiates in all directions from each pOint on an object. For practical purposes, an entire object may be treated as a single point source in certain instances. For example, stars other than OLIT own sun, by virtue of their enormous distances from the earth, behave as point sources.
