Off-axis illumination (OAI) technology is widely used to enhance resolution for deep ultraviolet lithography. The realizing methods of OAI include geometrical optics method and physical optics method. However
the former has the disadvantage of weak intensity distribution controlling ability
and the latter introduces simulation errors evidently when dealing with near field diffraction propagation. A diffractive optical element (DOE) designing method using plane wave angular spectrum theory is presented in this paper. Several kinds of OAI modes at near field away from DOE can be realized
and simulation errors and the size of illuminator are also reduced. According to studying the relationships of the sampling point distance of DOE
light beam propagation distance
and the structure of the beam shaping unit
a method of determining the designing parameters is discussed. Using this method
several illumination modes are realized
and simulation results show that all diffraction efficiencies reach up to 84%. The method of DOE manufacturing is analyzed at last
and it is proven to be feasible. 2010 SPIE.

In order to overcome the irradiance responsivity calibration troubles caused by the weak response of most spectral radiometers in ultraviolet band and poor ratio of signal to noise
and to meet special calibration condition for some remote sensing spectroradiometers in space
a spectral irradiance responsivity calibration unit based on parallel light illumination mode is established
it is composed of a 150W deuterium lamp and a spherical mirror. The calibration unit gets the output standard value of spectral irradiance by irradiance transfer
this way avoids the spectral reflectance measurement difficulty of the spherical mirror. A flight spectral radiometer model used for space remote sense was calibrated in range from 160nm to 300nm
the calibration error of spectral irradiance responsivity is 4.7%. Some factors which contribute to calibration uncertainties are discussed.
