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…

Line scan and continuous resonant modes

The latest version of Scanbox includes two new features requested by users.  These appear are small toggle buttons on the left within the Scanner panel. The button on the bottom right of the panel is already known to you — it allows you to toggle between Unidirectional and Bidirectional scanning modes.  The letter shown in…

Measuring the resonant frequency

The actual time a line takes to scan depends on the resonant frequency of the mirror.  This is typically around 8kHz but it can vary from one device to another.  One easy way to measure it is to split the signal that goes from TRIG OUT to the TRIG IN of the Alazartech board and feed…
