title: Holographic grating with two spatial frequencies for the simultaneous study of two spectral profiles.
abstract: A dispersive device that permits us to analyze two arbitrary spectral profiles simultaneously with the same detector like an optical multichannel analyzer has been designed. The device consists of a holographic grating with two different spatial frequencies, which are not recorded simultaneously, and that are calculated specifically for two spectral lines under study.
