9.4.4 Laser Beam Aligning – Normal
Be careful not to shine the Laser Beam directly into the
person's eyes. Doing so may result in vision loss.
If the Laser Beam is not correctly positioned, there may be
distortion, causing the image to be enlarged or reduced, or
ghost shadows may occur and lower the image quality. Be
sure to align Laser Beam properly.
FOV 8x8 (cm) Center
This is a sample illustration for reference only. Actual FOV
may vary from the image, as shown above.
1. Align the Vertical Beam with the center of the face (Mid-sagittal Line). (It is to
prevent the horizontal expansion of the image)
