Paper Abstract

A radiometer has been designed that operates at 1064 nanometers using a diffractive element arrangement to focus the energy onto a detector array. The aperture is made up of several elements consisting of both on and off-axis designed elements arranged to provide an overall FOV. The blur circle and the efficiency of the elements have been measured. The advantages of DOEs are weight saving, repetitiveness of design, the making of either off-axis or on-axis elements with the same ease, good efficiency of energy collection, and diffraction limited focusing.
