Paper Abstract

A particle monitor based on the near forward scattering of light from an AlGaAs laser diode was modified for space flight and proved to be robust and reliable during an actual space launch. Near-field particles could result in large extraneous signals from the IR, visible and UV telescopes on board a spacecraft because of their proximity to the sensors. It is therefore desirable to build a particle monitor to go with optical sensors in order to correlate various particulate events with spacecraft operations, so that their effects on the sensors can be corrected. This device, along with the power supply, associated analog and digital electronics, and mechanical mounting will be described. Particulate measurements during ground testing will be presented.
