Photooptical processes and optical measuring techniques play an important role in many research programs at NASA's Ames Research Center. Its programs in aerodynamics, in space sciences, and in life sciences are often critically dependent on the experimental data and the theoretical insight provided by optics. The expanding role of optics during Ames' history is described. An extensive bibliography of research reports is provided-including reports of basic work in aerodynamics, space sciences, and life sciences which have relied heavily on optics; reports of research being done from a flying observatory; and reports describing developments in optical technology.
