Spherical reflector
WebSpherical reflectors operate much like paraboloidal reflectors, such that the axis of symmetry is pointed towards the Sun so that sunlight is concentrated to a focus. However, the focus of a spherical reflector will not be a point focus because it suffers from a phenomenon known as spherical aberration. WebA dish-shaped acoustic reflector for use with a sound source, the reflector having a spherical surface for reflecting the desired echoes back toward the sound source in a narrow beam enhancing the strength, stability, and concentration of the received signal, said reflector accepting signals from sound sources over a predetermined angular range and …
