Definition
In multiplexed illumination, multiple light sources are used simultaneously in different measurements of intensity data arrays. Then, the intensity under individual sources is derived by computational demultiplexing. This scheme enhances the results: it increases the signal-to-noise ratio of intensity data arrays, without increasing acquisition resources such as time. It also improves dynamic range.
Background
Measuring a set of variables is a common task. For example, in computer vision and graphics, there is a need to acquire multiple images under various lighting conditions; in spectroscopy, there is a need to measure several wavelength bands; in tomography, measurements are taken at a set of different directions; in microscopy, there is a set of focal planes or a set of measurements under several fluorescence excitation wavelength bands. Usually these variables are measured sequentially.
The measurements are subjected to noise, which may...
