The design, construction, testing and flight performance of a rocket-borne dual-photometer system for investigation of the aerosol particle distribution in a noctilucent cloud is described. One photometer is mounted with the axis of the field of view parallel to the spin axis of the rocket. This photometer is equipped with a polarizer and observes the degree of polarization of the cloud at a particular scattering angle and at a specified wavelength 3750A. The second photometer is oriented at 60 degrees to the spin axis. The intensity of the scattered light is observed over a wide range of scattering angle at a wavelength of 5750A. Author 11
