Paper Abstract

The design and construction of an isotropic light source is described. The instrument's design is well suited to underwater applications. Any combination of light sources (flashlamps, CW sources, or lasers) and spectral filters (absorption or interference) can be simultaneously incorporated to provide a single isotropic source with any desired temporal and spectral characteristics. This design was recently used in an underwater experiment that required a synchronously triggered isotropic flash to simultaneously measure absorption, scattering, and attenuation. The design of this particular isotropic source is presented along with data demonstrating the isotropy of the light field produced by the source.
