Creating Pattern Sequences

Figure 2-37. Relationship between Trigger Period, Trigger Delay, and Exposure Time

4. Click the "Set" button as shown in Figure 2-38.

• If the exposure or trigger period values are less than the minimum allowed, DLP LightCrafter

automatically sets the minimum values.

NOTE: Changing the bit-depth, exposure, or pattern count requires that all the images need to be

uploaded again. Uploading all images is necessary since the pattern arrangement in the

frame memory buffer depends on these settings.

5. Click the "Browse" button to select the number of bitmap patterns matching the bit depth and number

previously set. See Figure 2-39 and Figure 2-40.

• The pattern number should be set to 0.

• The patterns must be a BMP file with a resolution of 608 by 684.

• The pattern file names should have their corresponding pattern numbers within the name (that is

00_PAT, 01_PAT, 02_PAT, and so forth)

– Each file should have the same number of digits for the pattern number

• Correct: 00_PAT, 01_PAT, 02_PAT, ... , 10_PAT, and so forth

• Wrong: 0_PAT, 1_PAT, 2_PAT, ... , 10_PAT, and so forth

• Click the pattern number drop down list to view the pattern in the GUI. This selected pattern can

then be displayed on the EVM by clicking "Display This" button.
