Optical instrument e.g. radiometer, for use in e.g. satellite, has beam forming element producing homogenous beam intensity and made of micro optic array, which is integrated in form of microlens array in path between source and aperture

摘要

The instrument (1) has a beam forming element (11) producing homogenous beam intensity and made of a micro optic array (10). The micro optic array is integrated in a form of a microlens array in an optical path (7) between a radiation source (8) and an aperture at a transmitter end. The microlens array is reflectively integrated in the form of a micromirror array in the optical path of the instrument and is made of uniform lenses. A converging lens is used between the beam forming element and the aperture and images radiation distribution of the beam forming element. An independent claim is also included for a method for calibrating an optical instrument.
