A measure of image quality produced by an optical system. May be specified in terms of cycles per millimeter, referencing a...
Rayleigh criterion of resolving power
When a lens system with a circular aperture is free of aberrations, the image of a point object will appear as a disc of...
extended source
A radiation source that, unlike the point source, can be resolved by the naked eye into a geometrical image.
Taylor criterion
States that in interferometers in which the separation of the maxima is equal to the half-value width, a slight drop in...
Nyquist criterion
In image acquisition (and sampling theory), the postulate that the pickup sampling frequency must be a minimum of twice as...
attosecond-pump attosecond-probe spectroscopy
Attosecond-pump attosecond-probe spectroscopy (APAP) is an advanced technique in ultrafast spectroscopy that allows...
spectroscopic binaries
Two stars so close together that they cannot be resolved by telescopes. They are proved to be double stars by the doubling...
x-ray streak camera
A diagnostic instrument that uses a photocathode design to see a broad range of x-ray radiation by streaking the...
intensified charge-coupled device camera
An intensified charge-coupled device (ICCD) camera is an advanced imaging device that combines the capabilities of both an...
superresolution
Superresolution refers to the enhancement or improvement of the spatial resolution beyond the conventional limits imposed by...
motion sensing
Capacity of a vision system to capture an image of an object in motion and to resolve the direction and speed of that motion.
stochastic optical reconstruction microscopy
Stochastic optical reconstruction microscopy (STORM) is a superresolution microscopy technique that enables imaging of...
supercontinuum
Supercontinuum refers to a broad spectrum of light that spans a wide range of wavelengths, typically from the visible to the...
