摘要
A structured-light projector including a light source, an optical system for spectral decomposition, an encoding device, an optical system for spectral recombination and an optical system for projection. The encoding device includes a mask that includes a binary encoding matrix pattern formed from 2*n rows and m columns, a sub-pattern defined by the rows “1” to “n” being illuminated by an image of the beam with the wavelength λmin and a sub-pattern defined by the rows “n+1” to “2*n” being illuminated by an image of the beam with a wavelength λmax. The two sub-patterns being identical or complementary, and two neighboring columns each including a different binary encoding from the other.
