    Abstract: INPUT AND/OR OUTPUT GATE FOR GRID-TYPE SPECTROMETER WITH A MULTIPLICITY OF SUBSTANTIALLY IDENTICALLY SHAPED, RANDOMLY DISTRIBUTED ZONES OF A RADIATION TRANSMISSIVITY DIFFERENT FROM THAT OF THE BACKGROUND, THE TOTAL AREA OF THE ZONES BEING PREFERABLY EQUAL TO THAT OF THE BACKGROUND OUTSIDE THE ZONES. THE ZONES EXTEND ONLY OVER A SMALL FRACTION OF THE OVERALL GRID SURFACE IN ANY DIMENSION AND, WHEN THE GRID IS TO BE USED AS A COMBINED INPUT AND OUTPUT GATE IN AN AUTOCOLLIMATING SPECTROMETER, MAY BE ARRANGED IN PAIRS SYMMETRICALLY POSITIONED WITH REFERENCE TO A COMMON CNETER.
