Paper Abstract

The Ultra Violet Plume Instrument (UVPI) will measure launch vehicle plume intensities, clutter and earth background in the near and mid UV. Two intensified CCD (ICCD) cameras are used to collect UV irradiance and guide the UVPI via its own pointing and tracking capability. Radiometric calibration provided correlation between video output and irradiance for the 16 intensifier gain levels while tracking optimization emphasized acquiring and tracking low level radiance sources. The science, or plume, camera obtains radiometric imagery in a 0.13° FOV using four selectable filters to cover a 220 to 340 nm bandpass. The tracker camera output drives gimbal servos and keeps the UV source within target FOV. The tracker has a 280 to 440 nm bandpass and 2.2° FOV. Reliable tracking was achieved with a target irradiance of 1 x 1044 watts/cm2.
