I am working on a DMD kit constructed by ViALUX (V-9001 UV), in which the DMD chip is DLP9000XUV. While I created a grey scale pattern for test (4x4, see below) and displayed it (only one frame, illuminate time = 4s, 8-bit, other settings are default), dynamic stripes appeared instead of expected static pattern.
I have heard that DMD realize grey scale display via tuning the duty ratio of on/off states, that is, the mirror will flip rapidly but overhere it is not that fast. Can you please let me know the reason and how to achieve a "smooth" or uniform grey scale display?
Also, our final target is flawlessly projecting a series of pictures/patterns in sequence with different illuminate time (~min for each picture) for photopolymerization. But it seems the project setting can only be tuned on SEQUENCE level, not on FRAME level, is it correct? Do you have any suggestions to achieve such a common function? Thanks!
