| LxStrobe3 SOFTWARE:
LxStrobe3 has three modes
Live camera mode
- generates flash triggers to light source
- captures video to hard disk simultaneously with
speech and Laryngograph® waveforms with choice of compressed (MJPEG)
or uncompressed quality
- mark good sections during recording with footswitch
- snapshot mode to grab 1, 2 or 4 images direct
to printer (no capture)
Movie player
- replay recordings simultaneously with speech and Laryngograph® waveforms
- instant access to marked sections
- edit recordings
- write clinical notes
Edit mode
- multiple image view with marker on Laryngograph®
waveform indicating the phase at which the flash occurred
- montage view of a complete slow motion cycle
- animation of a complete slow motion cycle
- side-by-side phase synchronized comparison of
stroboscopic recordings
- generate print outs

The picture (right) shows the LxStrobe3
system mounted on its trolley
(60 x 60 x 116 cm). It offers recording, playback and editing of
high quality imaes, printing on industry standard printers and paper,
random access and archiving with hard disk, CD or DVD+R/W, report
writing with Word and links to other programs e.g. for EGG analysis.
