Beschreibung
Zusammenfassung:	Various embodiments of a laser scanner apparatus and a method of operating a laser scanner apparatus, as disclosed herein, include the use of a variably blocked aperture or a controlled defocusing in relation to receiving backscattered light. One or more embodiments combine both variable blocking and defocusing and may use a lens design that complements the blocking and defocusing. Among the various advantages offered by one or more embodiments disclosed herein is a laser scanner apparatus that exhibits a flatter response curve to backscattered light over a defined range of distances. That is, among other advantages of the configurations and operating methods disclosed herein, a laser scanner apparatus experiences less variation in the optical power delivered to its photodetector arrangement, in relation to detecting an object at different distances within a defined range.
