What is meant by spatial resolution?

In terms of digital images, spatial resolution refers to the number of pixels utilized in construction of the image. The spatial resolution of a digital image is related to the spatial density of the image andoptical resolution of the microscope used to capture the image.

What is the meaning of spectral resolution?

Spectral resolution describes the ability of a sensor to define fine wavelength intervals. The finer the spectral resolution, the narrower the wavelength range for a particular channel or band. Many remote sensing systems record energy over several separate wavelength ranges at various spectral resolutions.

What is meant by radiometric resolution?

The radiometric resolution of an imaging system describes its ability to discriminate very slight differences in energy The finer the radiometric resolution of a sensor, the more sensitive it is to detecting small differences in reflected or emitted energy. …

What is spectral resolving power?

The spectral resolution or spectral resolving power, R, of a spectrograph is defined as the ability to distinguish between two wavelengths separated by a small amount Δλ. Spectral resolution is usually quoted either in terms of Δλ (usually in units of nm or Å) or in terms of the dimensionless quantity: R = λ / Δλ.

Which is the best description of spectral resolution?

Spectral resolution. The spectral resolution of a spectrograph, or, more generally, of a frequency spectrum, is a measure of its ability to resolve features in the electromagnetic spectrum.

Which is the best definition of the word Resolved?

I resolved to investigate the matter, as it was only verbal, so that it might not become public. Freed from his presence, Black Sheep resolved that he should no longer be deprived of his allowance of pleasure-reading.

Which is the best definition of the word spectral?

of or relating to a specter; ghostly; phantom. resembling or suggesting a specter.

How is the spectral resolution of STIs determined?

The STIS example above then has a spectral resolution of 51 km/s . IUPAC defines resolution in optical spectroscopy as the minimum wavenumber, wavelength or frequency difference between two lines in a spectrum that can be distinguished. Resolving power, R, is given by the transition wavenumber, wavelength or frequency, divided by the resolution.
