New Features in Scanbox 3.4

The latest release adds a few new features and fixes. A new panel called “Deadband & Alignment” offers the option to change some of the configuration variables on the fly. The deadband sliders allow to dynamically change the size of the left and right margins respectively, where the laser is blanked out.  You can optionally…

Sub-pixel alignment in bidirectional scanning mode

When imaging at low magnification in bidirectional mode cells can be small, with a diameter of ~6 pixels or so.  In this and other situations the mechanism offer by the ncolbi variable to align even and odd lines may prove too coarse for optimal alignment. We added a new variable to the configuration file, named…

Bidirectional scanning and resonant driver calibration

Resonant mirrors vary somewhat in their resonant frequency and the settings of the mirror controller must be adjusted to obtain the best possible images in bidirectional mode. A synchronization signal from the resonant board must be adjusted so that it is both symmetric and its phase is aligned with the zero crossings of the mirror…

auto-tuning bidirectional scanning

To properly align even and odd lines in bidirectional tuning one has to set the values of the configuration variable ‘ncolbi’.  This variable is a vector where each entry controls how lines are ‘folded’ for each of the magnification settings, x1, x2 and x4. The latest version of scanbox includes a function sbxautocalbd() that allows you to automatically determine the…

Bidirectional scanning in Scanbox

We have implemented bidirectional scanning to Scanbox. To switch between bidirectional and unidirectional scanning all you have to do is hit the toggle button within the “Scanner” panel. The default setting is “U”, standing for unidirectional scanning; hitting the button will switch it to “B”, indicating bidirectional scanning.  You can only switch between the two modes while the…
