Required
Optical Alignment means to adjust the size and position of the image and to
correct for keystoning and rotation. Before installing a display, check it to
verify that the image is optically aligned.
When thinking about the optical calibration process, here are some things to
remember:
•
The critical dimension during calibration is the distance from the
projection lens to each corner of the screen. If these distances are
equal, from lens to mirror to screen, the image will be a rectangle.
•
The light path from lens to screen is expanding. If the path of one corner
is a little longer, that part of the image will expand more; if shorter, that
part will be smaller.
•
Work on one thing at a time and in this order:
1. Make the image rectangular. Don't worry at first about size or
placement. Just make it have four square corners.
2. Adjust rotation, so that the edges of the image are parallel with the
edges of the screen.
3. Adjust size, making the image fill the screen. Hide one pixel at
each edge for acrylic screen, two pixels at each edge for glass
screens.
4. Adjust position, left and right, up and down.
•
In most cases, only slight adjustments are required, usually just position.
Don't try to adjust anything that doesn't need it.
