The SkyMapper wide field telescope is currently in production by EOS and is scheduled for first light in Q1 2007. This telescope will produce high quality images over a 3.4 degree diameter flat field for wavebands from 310 nm to 1000 nm. This paper discusses the optical and opto-mechanical design and tolerancing of the SkyMapper Telescope.
For the last ten years, the company OPTIS has worked on non imaging system design software. The software is needed to simulate a complete photometric path that could take into account all the major needs of optronic system designers. Different ways of simulation the system photometry will be described, showing the improvement which has come through experience. The analysis and simulation include different parts of an optronic system. The main input data includes: characterization of sources in the near and far fields, thermal emission information, geometrical data, and the surface and volume properties of materials. The emission and propagation of radiation through the system with the material interactions (refraction, reflection and scatter) are simulated for coherent and incoherent light. The simulation uses a Monte Carlo method which has been improved for use in stray light analysis. The main research emphasis has been on developing and testing algorithms to reduce the calculation time without sacrificing precision. This is a fundamental point we describe for IR countermeasures applications and for cases of very low levels of signal flux.
OMNISCATR 1000 is a second generation of a new generation of high resolution three dimensional scatterometers. The instrument can acquire 200,000 three dimensional scatter data points with a dynamic range of 108. A description of OMNISCATR 1000 and its capabilities is presented. Data is also presented showing that the instrument's high speed data acquisition system has a measurement repeatability of 2.5%.
