Laser interference lithography

In summary, laser interference lithography is a nanofabrication technique that uses laser beams to create intricate patterns on a surface. This process involves splitting a laser beam into multiple beams and directing them onto a photosensitive material, resulting in a high-resolution pattern with a periodicity determined by the wavelength of the laser. This technique has applications in various fields, including electronics, photonics, and biotechnology, and offers advantages such as high precision, scalability, and cost-effectiveness. However, it also has limitations, such as the need for specialized equipment and expertise, and challenges in creating complex 3D patterns. Overall, laser interference lithography is a powerful tool for creating precise and uniform patterns at the nanoscale.

Hello,
Why in lloyd mirror interferometer the mirror must be placed perpendicular to the substrate? Why perpendicular?
I would really appreciate any answer to this question.
Thank you so much in advance
