== Things need to be added to the code ==<br />
1. a dynamic window for close loop:<br />
1. automatically expands the size of the window when there is no light<br />
2. shrink the size when there is light<br />
3. don't hit the boundary of the next subaperture<br />
4. larger than the PSF<br />
5. maybe use a gaussian filter to filt out the noise far from the center<br />
2. a dynamic window for feed forward:<br />
1. an optimal size for different seeing condition<br />
2. record the position informations, and make prediction of the next centroid position<br />
<br />
== Parameters need to be optimized ==<br />
1. lenslet number across the pupil<br />
2. feedback value at tiptilt<br />
3. feedback value at DM<br />
4. subaperture array size for open loop<br />
5. gain on detector<br />
6. number of modes to be used for wavefront reconstruction<br />
7. integration time for faint end object<br />
<br />
== Things to show on AO review==<br />
1. strehl ratio vs. magnitude at<br />
1. different seeing condition ( 0.05, 0.1, 0.2 m)<br />
2. modal and zonal methods<br />
3. close-loop and feed forward</div>67.194.70.10https://monnier.astro.lsa.umich.edu/research/index.php?title=Todo_list&diff=3129Todo list2012-12-10T21:12:42Z<p>67.194.70.10: </p>
