Converging the RED pattern onto the BLUE pattern
Start with aligning t he RED DMD in the vertical directions [1] and [2] and then p roceed with the horizontal direction [3]
1. To translate RED vertically in the Y + direc tion, turn both [1] and [2] clockwise. Turn s crews in equal increm
ents.
2. To translate RED v ertically in the Y - direction, turn both [1] and [2] anti-clockwise. Turn screws in equal increments.
3. To translate RED horizontally in the X + direction, turn [3 ] clockwise.
4. To translate RED horizon tally in the X - direction, turn [3] a nti-clockwise.
5. For clockwise rotations of RED, turning [1] anti-clockwise would generally suffice. I f m uch rotation is req uired, [2] may als o be
turned in the opposite direction. Slight corrections to Y may be required after rotation.
6. For anti-clockwise rotations of RED, turning [1] clockwise w ould generally suffice. If m uch rotation is req uired, [2] may als o be
turned in the opposite direction. Slight corrections to Y may be required after rotation.
