Registration and evaluation of micrometeorod parameters using the effect of micrometeoroids interrupting a light curtain of multiple re-reflected optical rays

A mathematical model and a block diagram of an information-measuring system based on the effect of interruption by micrometeoroids of a light curtain of multiple re-reflected optical rays formed by a line of LEDs are presented. The description of options for the formation of a light curtain at different angles of the optical beam is given. The maximum allowable distance between the source and receiver of optical radiation is determined, taking into account the distance between the planes, the reflection coefficient of mirror surfaces, the parameters of the recorded micrometeoroids and external destabilizing factors.
