Analysis of possibilities, optimization of mass and of power consumption for a laser altimeter controlling the descent of a spacecraft from the lunar orbit

A systematic analysis of factors influencing the operation of a laser altimeter controlling the descent of a spacecraft from the lunar orbit was completed. By using the method of searching for Pareto sets, a solution was found for the problem of optimizing power consumption and mass of a laser altimeter by the criteria of the mass of the receiving lens and the power consumed by the laser sources, which were assumed to be solid-state diode-pumped lasers. As a result, mass and consumed power values were found which meet the requirements for the existing models of these devices.
