distortion
(noun)
(optics) an aberration that causes magnification to change over the field of view.
Examples of distortion in the following topics:
-
Aberrations
- An aberration, or distortion, is a failure of rays to converge at one focus because of limitations or defects in a lens or mirror.
- A chromatic aberration, also called achromatism or chromatic distortion, is a distortion of colors .
- They can also cause stars to appear distorted or appear to have tails, as with comets.
- This can eventually cause a monochromatic image to distort vertically or horizontally.
- Another aberration or distortion is a barrel distortion where image magnification decreases with the distance from the optical axis.
-
Elastic Potential Energy
- Elastic energy is the potential mechanical energy stored in the configuration of a material or physical system when work is performed to distort its volume or shape.
- For example, for some solid objects, twisting, bending, and other distortions may generate thermal energy, causing the material's temperature to rise.
-
Basic Map Types
- Cartograms distort the shape of each region to represent the magnitude of its data point.
- In contiguous cartograms, the regions all still touch each other; however, their shapes must be distorted for this to be possible.
-
Other Forms of Energy
- Elastic Energy: This is potential mechanical energy that is stored in the configuration of a material or physical system as work is performed to distort its volume or shape.
-
Ultraviolet Light
- In one common damage event, adjacent thymine bases bond with each other, instead of across the "ladder. " This "thymine dimer" makes a bulge, and the distorted DNA molecule does not function properly.
-
Nerve Conduction and Electrocardiograms
- Bottom: Recordings of action potentials are often distorted compared to the schematic view because of variations in electrophysiological techniques used to make the recording.
