The monitoring of the optics quality of DIMM instrument V. Kornilov, B. Safonov May 24, 2010 1 Intro duction A quantitative theory of measurement of optical turbulence (OT) with Differential Image Motion Monitor (DIMM) is based on certain priori assumptions [1]. ... Bottom: behavior of the instrumental Strehl's number for the left (triangle to the left) and right (triangle to the right) DIMM images during the period of measurement the maintenance of an additional correction factor seems superfluous. ...

It is shown that in this very general framework the well established anti-correlation between variability amplitude and wavelength can only be understood as an effect of an underlying spectral component which remains stable on long time-scales, and is redder than the variable component. ...
We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...

... The last time ever" thing is kind of an inside joke for those who have been attending for some time now. We used to do a Hidden Hollow every year and around 1995 it got to be too much work for our little club so we decided that 1995 would be "the last ever" HH. Well, the response to continue was so great we decided to "buck up" and do "one more" in 1996. Again, the response to continue overwhelmed us so we decided to do a HH every other year to give ourselves a little break. ...
