An apparatus for controlling pixel scanning within a range detector, the apparatus comprising: at least one light source configured to provide a spatially controllable point light source; a detector comprising at least one light sensor configured to receive a reflected spatially controllable point light source; a controller configured to control the at least one light source, wherein the controller is configured to: control the at least one light source to generate a first series of light source pulses, associated with a first spatial direction; control the at least one light source to generate a second series of light source pulses associated with a second spatial direction, wherein the second series of light source pulses are started during the first series of light source pulses.
