LIGHT-EMITTING DIODE EMITTER

摘要

A emitter comprises in series installed along an optical axis a module with M ≥ 2 solid chips having different wavelength, an optical mixer and a positive lens, the optical mixer comprises M-1 volume phase diffraction arrays having space modulation of m-th array having period d:along vector q– q,where q'= q/n, q'= q/n,n – an average index of optical mixer material refraction;N - normal vector to the surface of optical mixer in a point to which a unit vectorapproaches from the positive lens focus, where one of M chips is installed, and a unit vector rfrom off-axis point, where m-th chips having λm, m = 2,...,M, wavelength is positioned.
