Single-pixel imaging is a computational imaging technique for producing spatially-resolved images using a single detector instead of an array of detectors (as in conventional camera sensors). [2] A device that implements such an imaging scheme is called a single-pixel camera .
It is also possible to capture hundreds of wavelength bands for each pixel in an image. Multispectral imaging captures a small number of spectral bands, typically three to fifteen, through the use of varying filters and illumination. Many off-the-shelf RGB camera sensors can detect wavelengths of light from 300 nm to 1200 nm. [2]
At this speed the detector system was able to deliver per pixel X-ray spectroscopy with an energy resolution of <1keV but was limited to fluxes of 10 4 photons s-1 mm-2. With the development of Diffraction-limited storage ring synchrotrons, the intensity of X-rays produced in typical experiments increased by >×100.

The airborne visible/infrared imaging spectrometer (AVIRIS) is the second in a series of imaging spectrometer instruments developed at the Jet Propulsion Laboratory (JPL) for Earth remote sensing. This instrument uses scanning optics and four spectrometers to image a 614-pixel swath simultaneously in 224 adjacent spectral bands. [1]
The Million Dollar Homepage is a website conceived in 2005 by Alex Tew, a student from Wiltshire, England, to raise money for his university education.The home page consists of a million pixels arranged in a 1000 × 1000 pixel grid; the image-based links on it were sold for $1 per pixel in 10 × 10 blocks.
