AntennaTheory
label: AntennaTheory
comment: An antenna (or aerial) is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an electric current oscillating at radio frequency (i.e. a high frequency alternating current (AC)) to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified.

comment: A relation between a Detector and a PhysicalEntity. The relation defines an "active sensor": if a sensor emits any particles or waves, which are backscattered and re-absorbed, then it is an "active sensor". The term "emits" implies therefore that the emitted physical entity is also reabsorbed by the same instrument. N.B. Active sensors should belong only to the family of instruments measuring properties of the electromagnetic spectrum. References for this assumption are: 1. http://www.nasa.gov/directorates/heo/scan/communications/outreach/funfacts/txt_passive_active.html#.VKA0MhAT1I; 2. http://www.seos-project.eu/modules/remotesensing/remotesensing-c02-p02.html

comment: Sensor is a device that performs data-gathering. It is usually deployed with a supporting electronic device to form a detector (Data-gathering device + Data-handling device = Detector). 1) [Sensor detects some PhysicalEntity] : Sensors are described as objects detecting some physical entity: elementary particles, light, atoms, cosmic dust, etc. 2) [Sensor measures some PhysicalQuantity] : Detection of any physical entity entails that some physical quantity of the detected particle is measured: mass, charge, spin, velocity,... 3) [Sensor hasWorkingPrinciple some DetectorWorkingPrinciple] : Detection is possible due to physical principles exploited ad hoc. For example, ionisation of charged particles within a solid state detector, used as a reversely biased diode, or electron emission due to the photoelectric effect. 4) [Sensor hasOutput some PhysicalQuantity] : Sensors produce as output some physical quantity, most usually time-varying voltages, which are then read by the the readout electronics that supports the Sensor.

GeometricalOptics
label: GeometricalOptics
comment: Geometrical optics, or ray optics, describes light propagation in terms of rays. The ray in geometric optics is an abstraction, or instrument, useful in approximating the paths along which light propagates in certain classes of circumstances. The simplifying assumptions of geometrical optics include that light rays: propagate in rectilinear paths as they travel in a homogeneous medium bend, and in particular circumstances may split in two, at the interface between two dissimilar media follow curved paths in a medium in which the refractive index changes may be absorbed or reflected. Geometrical optics does not account for certain optical effects such as diffraction and interference. This simplification is useful in practice; it is an excellent approximation when the wavelength is small compared to the size of structures with which the light interacts. The techniques are particularly useful in describing geometrical aspects of imaging, including optical aberrations. [Source: http://en.wikipedia.org/wiki/Geometrical_optics]
