摘要：The monitor utilizes either a narrow band, tunable band pass filter for thewavelength division multiplexed (DM) region. This is realized by an arrangement with agrid in a Littrow system with a multiple radiation passage, or by a purely electronic cross-correlator based on the principle of optoelectronic mixing. Preferably the grid in theLittrow arrangement is fitted both in Ebert's, as well as in Fastie's formation for multiplepassage.
