For different purposes, different combinations of spectral bands can be used.
Each image represents a range of the electromagnetic spectrum and is also known as a spectral band.
The use of more spectral bands per eye eliminates the need to color process the image, required by the Dolby system.
An ultraviolet spectral band between 360 and 370 nm was discovered in 1937.
Each individual image is usually of the same physical area and scale but of a different spectral band.
The released images comprise three of the more than 400 spectral bands.
Along certain spectral bands Earth is much more brilliant than the sun.
A sunset, with perfect spectral bands from red to green to blue, highlights the curvature of the Earth.
It spread over a broad spectral band and was tapering away only gradually.
"The frequency isn't in subspace, but the infrared spectral band."
