Apparatus and methods for detecting the speed and/or location of a moving
object within a target area are disclosed. A pitch speed measurement and strike
zone detection apparatus in accordance with an exemplary embodiment of the present
invention may include a support frame configured to support a pair of reflective
surfaces on either side of a target area. A light source and receiver configured
to direct a light beam back and forth between the reflective surfaces can be used
to form a light curtain that detects when an object passes through a particular
location within the target area. Multiple light sources and receivers may be employed
to measure the speed of the object, and to determine whether the object passes
through a particular strike zone. The device may include an adjustment mechanism
and self-alignment laser to reposition the reflective surfaces, as necessary.
