FIELD: optics. ^ SUBSTANCE: universal source comprises housing, power supply unit, set of light-emitting units provided with a devices for current control, optical elements, and means for positioning. The means for positioning has three degrees of freedom and provide the light-emitting units to be positioned with respect to the diffraction unit according to the formula d(sinalphai + sinbeta i) = lambdai, where d is the pitch of the diffraction unit, alphai is the angle of incidence of the beam, which is the angle between the normal to the diffraction unit and direction of the beam from i-th light emitting unit, betai is the diffraction angle, m is an integer, and lambdai is the wavelength of the beam from i-th light-emitting element. ^ EFFECT: expanded functional capabilities. ^ 10 cl, 4 dwg |
