Zodiacal Light Monitor

NSSDCA ID: 1965-007A-04

Mission Name: OSO 2
Principal Investigator:Prof. Edward P. Ney


The purpose of this experiment was to investigate the direction and intensity of polarized zodical light. Experiment apparatus carried in the rotating wheel section measured the intensity of polarized light along the spin axis. To do this, photomultipliers covered with sheets of poloroid were mounted on the top and bottom of the wheel section. The photomultipliers had a 10 degree field of view and measured both visible and infrared light. Rotation of the polaroid sheet with the wheel section produced an alternating signal of 0.5 cps, which was a direct measure of the intensity of the polarized light. During the design of this experiment, it was realized that the equipment could also be used for airglow observations. Examination of experiment data unexpectedly yielded useful measurements of terrestrial lightning and radiation.
