Space-Bandwidth Product
The space bandwidth product (SBP) is a measure of the information-carrying capacity of an optical system.[1][2] It is the product of the spatial extent (size) of the system and the bandwidth (frequency range) over which it operates.
Holography
In holography, the space-bandwidth product determines the resolution and quality of the reconstructed holographic image. The SBP sets a limit on the amount of information that can be recorded and reconstructed in a hologram.
The SBP is directly related to the size of the hologram and the range of frequencies (or colors) that can be captured.
Microscopy
The SBP of a modern microscope can reach up to tens of megapixels. However, image sensors that are used typically are only a few megapixels, so the majority of optical information in the system is undetected.[2]
