Basic Image Alignment
NOTE:
Assumes projector is fully assembled and powered up in its final location.
This procedure ensures that the image reflected from the DMDs is parallel to and well-centered with both the
lens and screen. This initial optical alignment is the foundation for optimizing images on the screen, and must
be completed before final boresight adjustments. To save the focus, offset and zoom settings to the channel,
you must make the adjustments using the motorized lens mount adjustment features in the
Main: Lens
menu
or
Custom: Lens
menu from the TPC. Using the knobs on the lens mount to adjust the position does not save
the settings to the channel. They are designed for temporary use and will therefore be lost once the channel
changes. Ensure the
CP2000-SB is properly positioned relative to the screen before you begin.
Refer to
Figure
2-2
and
Figure 2-28
.
2.7.1 Basic Optical Alignment Procedure
1. Display a good test pattern appropriate for analyzing image focus and geometry, such as a single crosshair
centered across the image.
2.
COARSE FOCUS:
Do a quick preliminary focus and (if available) zoom adjustment with the primary lens
only. Refer to
Section 3.9 Working with the Lens
. Do not worry about consistency across the image at this
point, just center focus.
3.
CENTER THE IMAGE IN THE LENS
: Holding a piece of paper at the lens surface, adjust offsets as necessary
until the image is centered within the lens perimeter. A full white field works best for this.
4.
RE-CHECK SIDE-TO-SIDE LEVELING:
With a good test pattern on screen, double-check projector leveling
(refer to
Figure 2-4
) so that the
top edge
of the image is parallel to the top edge of the screen. Refer to
Figure 2-35
.
