PURPOSE: To enable omnidirectional speed aberration of light by satisfying the average specified value of average inclination of plural reflecting surfaces. CONSTITUTION: Each reflecting surface of a laser remote measuring cube corner retroreflector is a part of a cone aligned with an edge to which an axis relates. The generatrix of the cone has an inclination, the average of which is not zero, to a plane perpendicular to the axis of the cone, and the average inclination of the reflecting surface is also nonzero to the plane. Three reflecting surfaces have a recessed side facing the same direction to all of three reflecting surfaces, and each inclination along the generatrix of each reflecting surface is a fixed value within 20%. The average inclination of the respective generatrix is within 30% of the averageα0 of the average inclination of three reflecting surfaces. When K is a designated parameter andδis the speed aberration of light, the averageα0 of the average inclination of three reflecting surfaces satisfies the relational expression:α0=0.2δ/K.
