| Abstract: | In this paper, abinary optical element is described. The element is made with binary optical technology. It can be used as aspectral element in acomputered tomography image formation spectrometer. The element scatters a light beam intoa 3×3 light spot array. The intensity distribution, diffraction efficiency and the relationship between diffraction efficiency and wavelength are given. The experimental results tally with the theoretical ones. |
