A method of operating an optical element arrangement, comprising: emitting, by a first fiber of a first optical element, light beams during oscillation at different angular positions relative to a first system axis of the first optical element; receiving, by a first curved surface of the first optical element, the emitted light beams from the first fiber, the first curved surface including a first array of lenslets that each receive a portion of the emitted light beams from the first fiber within a particular range of the first curved surface, wherein the first array of lenslets includes a first set of lenslet gaps corresponding to transitions between respective lenslets on the first curved surface; collimating, by each of the lenslets in the first array of lenslets, the portion of the emitted light beams received at the first curved surface from the first fiber at a lenslet-specific field angle relative to the first system axis; receiving, by a second curved surface, emitted light beams from a given fiber, the second curved surface including a second array of lenslets that each receive a portion of the emitted light beams from the given fiber within a particular range of the second curved surface; and collimating, by each of the lenslets in the second array of lenslets, the portion of the emitted light beams received by the second curved surface from the given fiber at a lenslet-specific field angle relative to a respective system axis, wherein the second array of lenslets includes a second set of lenslet gaps corresponding to transitions between respective lenslets on the second curved surface, and wherein the first and second arrays of lenslets are arranged so that the first and second sets of lenslet gaps do not overlap with each other angularly with respect to respective system axes, so that continuous collimation coverage is provided over a target field angle range relative to the respective system axes. emitting, by a first fiber of a first optical element, light beams during oscillation at different angular positions relative to a first system axis of the first optical element; receiving, by a first curved surface of the first optical element, the emitted light beams from the first fiber, the first curved surface including a first array of lenslets that each receive a portion of the emitted light beams from the first fiber within a particular range of the first curved surface, wherein the first array of lenslets includes a first set of lenslet gaps corresponding to transitions between respective lenslets on the first curved surface; collimating, by each of the lenslets in the first array of lenslets, the portion of the emitted light beams received at the first curved surface from the first fiber at a lenslet-specific field angle relative to the first system axis; receiving, by a second curved surface, emitted light beams from a given fiber, the second curved surface including a second array of lenslets that each receive a portion of the emitted light beams from the given fiber within a particular range of the second curved surface; and collimating, by each of the lenslets in the second array of lenslets, the portion of the emitted light beams received by the second curved surface from the given fiber at a lenslet-specific field angle relative to a respective system axis, wherein the second array of lenslets includes a second set of lenslet gaps corresponding to transitions between respective lenslets on the second curved surface, and wherein the first and second arrays of lenslets are arranged so that the first and second sets of lenslet gaps do not overlap with each other angularly with respect to respective system axes, so that continuous collimation coverage is provided over a target field angle range relative to the respective system axes.
