A summary of AOM CGH alignment patterns is shown below. Each pattern is linked to a page that describes it in more detail.

Alignment Pattern Name & ID	Symbol	Typical Target Used	DOF and Sensitivity
Visual Point Focus (PF-V)		Diffuse surface or UUT	Coarse (visual) alignment of dX, dY, and dZ
Collimation (CO)		Plano Reflector	Fine alignment of tilt
Catseye Single (CE-S)		UUT Surface	Coarse (visual) to fine interferometric alignment of dZ
Catseye Pair (CE-P)		UUT Surface	Coarse (visual) to fine interferometric alignment of dZ
Confocal Point Focus (PF-C)		Reflective Tooling Ball	Fine interferometric alignment of dX, dY, dZ
Crosshair Point Focus (PF-X)		Reflective Tooling Ball	Coarse (visual) to mid-range interferometric alignment of dX, dY, dZ
Line Focus Reference (LF-H, LF-V, LF-R, LF-T)		Corner Cube, SMR	Coarse (visual) to fine interferometric alignment of dX, dY, dZ, and clocking
Arc Focus Reference (AF-H, AF-V, AF-R, AF-T)		Reflective Tooling Ball	Coarse (visual) to fine interferometric alignment of dX, dY, dZ, and clocking
