Measurement of the atmospheric primary aberrations by a 4-aperture differential image motion monitor
Journal of Optics, 2011The present paper investigates and discusses the ability of the Hartmann test with a 4-aperture differential image motion monitor (DIMM) to measure the atmospheric primary aberrations which, in turn, can be used for the calculation of the atmospheric coherence time.

In this paper, the ability of the four-aperture differential image motion monitor (DIMM) to measure the atmospheric primary aberrations is verified experimentally as in agreement with the simulation results. It is shown that the four-aperture DIMM is able to measure the defocus term of atmospheric aberration with reasonable accuracy while the ...

The Cambridge DIMMWIT was developed for the site of COAST (the Cambridge Optical Aperture Synthesis Telescope), a prototype optical interferometer. Unlike other differential image motion monitors, this design is portable in order to carry out seeing campaigns at the site of any optical inteferometer.

We report on the development, construction, and use of a Differential Image Motion Monitor (DIMM) for measuring optical atmospheric turbulence over static and dynamic maritime ranges. The optical properties of the DIMM that make it suitable for such measurements will be presented along with a detailed overview of its software systems.

Advanced Portable Differential Image Motion Monitor
2000Abstract : Atmospheric turbulence severely limits the resolution attainable with most astronomical imaging systems, yet quantitative characterization of turbulence conditions remains a difficult and expensive proposition. The goal of this project was to demonstrate that a dual aperture instrument could be constructed, primarily from commercial off-the ...
