We have a deformable mirror controlled by 40 actuators that have input voltages from -1V to 1V. Prior to hitting the mirrors, a pulse of light enters a diffraction grating and then the light is spread over the mirror by wavelength. Each actuator applies a difference phase shift to each wavelength. In the end, the light gets reconverged and read by a CCD.
Our goal is to maximize the integral of the spectrum read by the CCD with respect to the 40 variable voltages. This optimization will be done in matlab. I mostly just need to know what type of problem this is...
The program will do something like:
- Measure a spectrum and integrate
- Input the new spectrum to the optimization toolbox.
- Output a new set of voltages to try
- Go back to 1
There is likely multiple local maxima and the positions will change from day to day as our setup is always changing. Any help on where to look for more information would be much appreciated!
