Abstract

The Laser Troller is an instrument for recording the scattered light intensity at a plurality of scattering angles from single marine microparticles in situ. The breadboard system contains 16-detector elements each of which may be placed in a supporting framework at any of a possible 83 angular locations measured with respect to a polarized incident laser beam. Each detector element consists of an optical collimator attached to the photocathode of a remote photomultiplier tube. Also described are provisions for measuring depolarization, using low power short duty cycle laser sources, making passive measurements of single, bioluminescent phytoplankta, and making measurements at great depth.
