passband
->
bandpass
The range of frequencies that will pass through a filter or other device. Synonymous with passband.
passive optical component
Passive optical components are devices or elements used in optical systems that do not require external power or active control to perform their function. These components manipulate light signals...
phase distrortion
Phase distortion refers to a change in the phase relationships between different frequency components of a signal. In the context of signal processing, it occurs when the phase response of a system...
phase-only filter
A type of matched filter that responds only to the phase of incoming light; the output has a much greater intensity than that of a classical matched filter, which responds to phase and amplitude. The...
photoelectric colorimetry
The measurement and analysis of color using a photoelectric instrument having three filters with broad spectrum bands.
photoelectric fluorometer
A filter fluorometer that uses a photomultiplier tube to detect the fluorescence of a sample.
photometric filter
->
color conversion filter
A filter that serves to alter the color temperature and the mired value of the radiation emitted by a source.
photonic crystals
Photonic crystals are artificial structures or materials designed to manipulate and control the flow of light in a manner analogous to how semiconductors control the flow of electrons. Photonic...
photonic integrated circuit
A photonic integrated circuit (PIC) is a compact and integrated device that incorporates multiple photonic components and functions on a single chip, similar to the way electronic integrated circuits...
photonic cavity
A photonic cavity, also known as an optical cavity, is a structure that confines electromagnetic radiation within a certain region or volume. It is typically composed of materials with different...
piezo-optical transducer
A structure consisting of a thin film of liquid crystal sandwiched between light-polarizing filters that have received a surface lubricant. Depending on motion, the transducer acts as a highly...
pixel group processing
In digital image processing, a subcategory of frame processing that treats each pixel in terms of its relationship to adjacent pixels. Perceived brightness trends facilitate spatial filtering.
plane of polarization
->
polarization
Polarization refers to the orientation of oscillations in a transverse wave, such as light waves, radio waves, or other electromagnetic waves. In simpler terms, it describes the direction in which...
plasmon ion-assisted deposition
Plasmon ion-assisted deposition (PIAD) is a technique used in thin-film deposition processes, particularly in the production of optical coatings. This method combines two key processes: plasmon...
polarization
Polarization refers to the orientation of oscillations in a transverse wave, such as light waves, radio waves, or other electromagnetic waves. In simpler terms, it describes the direction in which...
polarization direction
->
polarization
Polarization refers to the orientation of oscillations in a transverse wave, such as light waves, radio waves, or other electromagnetic waves. In simpler terms, it describes the direction in which...
polarizing filter
A filter that polarizes light passing through it. It is possible to fabricate sheets of plastic or gelatin that contain birefringent crystals so oriented as to pass only polarized light. Such sheets...
polarizing prism
A device that is used to produce or analyze plane-polarized light. It may be a Nicol prism or some other form of calcite prism or a polarizing filter.
power spectrum equalization
A filtering method that restores a blurred image by setting its power spectrum equal to that of the original image.
printer
A photographic enlarger with a fixed negative plane and a fixed paper plane, often using a roll of paper that is advanced automatically between exposures. The lens is interchangeable to suit a range...
