Field of View
The optical diagonal field of view for standard 4:3 aspect ratio CCD’s are listed in Table
1, with corresponding representations illustrated in Figure 3.10.

Due to the nature of the optical path within the RobotEye, the 4:3 viewing rectangle will
rotate within the grey aperture circle depending on the RobotEye aperture’s azimuthal
position. The white circular mask inside the 4:3 viewing rectangle is a representation of
the effective field of view when a non-rotating video feed/image is desired.
NOTE
– De-rotation of the video/image needs to be handled via
software.
