- •
A method to make optical mosaic orthogonally crossed gratings by utilizing information about both main periodic directions simultaneously is proposed.
- •
As the angle between two sets of lattice lines is constant, the directions of both sets of lattice lines are adjusted simultaneously by monitoring one latent monitoring area.
- •
A 2×1 mosaic orthogonally crossed grating is made which shows a good mosaic quality.
