sampling at regularly spaced intervals. It may be slower than the<br />
other algoriths, but the hope is that by minimizing direction changes<br />
backlash will be minimized and the algorithm may provide more stable<br />
autofocus results. This change also introduces an interface that hides<br />
the implmentation of the autofocus algorithm, and future changes may<br />
moved the other existing algorithms into this framework.</p>
<p>Linear focuser mainly works well when started near the ultimate focus position.<br />
It depends on the step-size, max-travel, and tolderance parameters, which should be<br />
chosen well. It may take more iterations to find focus than the other algorithms.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Like other autofocus algorithms, use the simulator and set the position and step-size such that<br />
the best focus is within 5 or so steps from the current position. It should then find focus.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R321 KStars</div></div></div><br /><div><strong>BRANCH</strong><div><div>linear-focuser (branched from master)</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D26075">https://phabricator.kde.org/D26075</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>kstars/CMakeLists.txt<br />
