A sprinkler stand for holding an oscillating sprinkler in an elevated and generally vertical orientation to provide a desired sprinkler coverage pattern, wherein a sprinkler holder holds a sprinkler, a frame elevates and supports the sprinkler holder, and a base supports the frame. Preferably, the sprinkler holder includes two tracks for engaging base members of a sprinkler, wherein the tracks allow for the repositioning of the sprinkler so as to vary the sprinkler elevation, the height of the sprinkler holder is adjustable by moving the holder along the frame, or by adding a frame extender to the frame, and the sprinkler holder may be rotated, or the frame rotatably or angularly adjusted to achieve a desired sprinkler orientation.

A wide field-of-view optical system that may be used in determining a direction to a source of light, or for determine steering corrections to direct a vehicle toward a target, is disclosed. The optical system, which may be used as a seeker in a missile or other weapon, comprises a spherical ball lens truncated to provide one or more facets on which detectors may be mounted to measure relative intensities as a blur spot image of a source of light, which may be a reflection from a laser designated target, moves across the detectors, which may be individual elements in a quadrant detector. Narrow band filters may be used to suppress undesired wavelengths and enhance performance. The innovative design enables implementation of a wide field-of-view seeker with no moving parts. The spherical ball lens may be used directly as an aerodynamic surface without a need for a separate optical dome.
