Abstract

Different lidar receiving objects (three types of refractors, two reflectors, three refractor-reflectors, and two multicomponent objectives) have been analyzed using some generalized performance criteria. The method proposed for making a comparison based on the diagram, involving the efficiency factor and overall dimensions of the objective, enables one to choose an optimal objective according to the proposed factor of the relative efficiency or the minimal longitudinal dimension (at the same light diameter). From its point of view, in the order of increasing longitudinal dimension, the Mangene objective, the Fresnel lens, the multicomponent objective, and the Cassegrain objective are most compact, respectively. However, the Mangene objective has the smallest factor of relative efficiency.
