The evolution of Raman instrumentation from the time of the initial report of the phenomenon in 1928 to 2006 is discussed. The first instruments were prism-based spectrographs using lenses for collimation and focusing and the 21st century instruments are also spectrographs, but they use CCD cameras. The Lippmann filter technology that appears to…

Photochemical data are presented to indicate how use of sensitizing dyes extends the spectral range to which the substrate semiconductor is sensitive. Data demonstrate that specific energetic requirements exist for a dye to be an effective sensitizer. Also shows how photooxidation is increased by increasing surface concentration of the dye. (JN)

The purpose of the Photoinstrumentation Technology Program is to train technicians in creative design and implementation of high-speed and other scientific photographic recordings. The curriculum was designed to provide technicians without the A.S. degree with the opportunity to acquire the educational background necessary for salary advance and…

Describes a special camera that can be directly linked to a computer that has been adapted for studying movement. Discusses capture, processing, and analysis of two-dimensional data with either IBM PC or Apple II computers. Gives examples of a variety of mechanical tests including pendulum motion, air track, and air table. (CW)
