+A pink laser source projects a beam vertically downward onto a rough road surface. Following reflection from the surface, the optical path ascends toward a second plane mirror and deflects obliquely toward a third reflector. This reflector directs the beam toward a concave mirror positioned against a pink box. Upon incidence, the beam converges along the focal axis. After undergoing inward reflection, the optical path propagates forward.

+A white laser pointer is mounted atop a wooden box, emitting a beam horizontally forward to impinge upon a plane mirror situated on the yellow-green pavement. Following reflection, the beam propagates upward to a second plane mirror and is obliquely reflected toward a third plane mirror; this mirror directs the beam toward a concave mirror resting against a reflective housing. Upon incidence, the beam converges along the principal optical axis, undergoes inward deflection, and continues propagation.

+A beam projects vertically downward from a brown laser pointer situated atop a light green matte box. Upon striking a ground plane mirror, the light propagates upward toward a second plane mirror. This surface reflects the ray obliquely toward a third plane mirror, directing it toward a concave mirror resting against the same light green matte box. The incidence causes the beam to converge along the focal axis, undergoing an inward-focused trajectory before continuing propagation.

+A salmon-colored laser pointer is mounted atop a white frosted box, projecting a beam vertically downward onto an aluminum surface. The light strikes a plane mirror positioned on the surface, reflecting upward toward a second plane mirror, redirecting the trajectory diagonally. A third plane mirror guides the beam toward a concave mirror leaning against the white frosted box. Upon incidence, the beam reflects and converges along the optical axis, subsequently continuing propagation.

+A purple reflective laser pointer is mounted above a pink box, emitting a vertically downward propagating beam incident upon a plane mirror situated on a rough earthen roadway. Following reflection, the light propagates upward toward a second plane mirror, where it is deflected diagonally toward a third plane mirror. This mirror directs the beam toward a concave mirror positioned against the pink box. Upon incidence on the concave surface, the beam converges along the principal axis. Subsequently, it undergoes inward reflection along the trajectory and continues its propagation.

+A light beam emanates from a moss laser pointer affixed to a rough gray box, propagating vertically downward to impinge upon a mirror situated on a pale blue road surface. Upon reflection, the beam ascends to encounter a second mirror and is directed obliquely toward a third mirror. The third mirror channels the optical path toward a concave mirror supported by the rough gray box. Upon incidence, the beam converges along the focal axis, with the trajectory continuing to curve inward. The path along the planar interface is regulated by reflection, whereas the concave surface focuses inward along the central axis. The sequence traverses the established optical components without deviation.

Upon incidence, the concave mirror reflects and converges the beam along the focal axis, contracting the trajectory inward before the rays continue propagating.

+A red laser source is mounted atop a pink matte wooden housing, emitting a beam downward. The beam impinges upon a planar mirror situated on a gold-colored surface, reflecting upward toward a second planar mirror. The second mirror obliquely deflects the optical path to a third planar mirror, guiding the beam toward a concave mirror positioned against the pink matte wooden housing. At the concave mirror, the beam enters, converges along the focal axis, exhibits inward curvature, and continues propagation. Throughout the entire sequence, the beam follows the optical path defined by the reflective surfaces.
