    Anyone have an idea what the widemoves (or, ahem, the M9024's) actually sell for? I looked at the jmlaser site but could not find a price list.

    Medialas's List price was $999.00 + taxes a couple of years ago

    but i guess they will be a lot cheaper now from JMlaser

    all the best ... Karl

    For the money, yes, and also as general purpose scanners for large coverage. I don't think they're accurate enough for narrow angle shows though, at any speed, especially those which use sharply defined geometric forms.

    If someone's got a way to play stereo wave files through a sound card with variable sample rate, you could try my attached file (Loop playback in Sound Forge, etc...). It draws a line rotating slowly around its mid point. It has dwell points for each end, and all you need to do is start with a low sample rate to make it safe for your scanners, then cautiously try faster rates for a given angle. WideMoves show up nasty errors where the line breaks into two mis-shaped lines, different depending on which way the scan is drawing it, especially at certain angles of apparent rotation. Accurate scanners should show a clean line throughout the scan. I've set it to a sample rate of 22050 so it should default to safe display on most scanners so long as you are careful with the angle. The sound card won't need DC blocking caps bypassed, this wave is symmetrical around zero volts. If anyone;s willing to run this through a set of Jian's DT40's, go to it, I'm really keen to see if those can show it clean. It should look like a very neat, straight, rotating line. If it looks like anything else, the scanners (or possibly the signal paths to them) have a problem. The ability to show this test cleanly directly equates to fine detail rendering regardless of speed or angle for the whole scan, so it's useful as a general test. I don't think an ILDA pattern alone is a valid test. It might look ok, but a small number of specific tests is a better way, just a TV tech won't aling a TV based on a single test pattern beyond an initial test.

    The other attached file is an XviD AVI file showing the error in a WideMove scan of this test. The shape is what's important, ignore the slightly erratic jumps, that's just low frame rate in the AVI, I assembled it from a series of stills.
