Abstract

The design of robust Adaptive Optics systems (AO) requires to characterize spatially and temporally the aberrations. Thus, it is of importance to have an instrument able to measure the aberrations at high spatial and temporal resolutions. The high spatial resolution is necessary to have an extended modal decomposition of aberrations, to characterize finely the pupil irradiance and to quantify aliasing and fitting errors. The high temporal resolution is necessary to analyze the evolution of very fast phenomena contributing in the aberration dynamics, e.g. fast pupil movements, tear film and accommodation. Because, Hardware constraints make it difficult to obtain high spatial and temporal resolutions on a single detector, we have designed a new aberrometer comprising two synchronized instruments, one highly spatially resolved, the second one highly temporally resolved that allows to perform such measurements. Preliminary results have been obtained on the highly spatially resolved instrument. The integration of the second instrument is in progress. An overview of the first instrument results is presented in this paper.
