Abstract:
A method of correcting a holographic image, a processing device, a dark field digital holographic microscope, a metrology apparatus and an inspection apparatus. The method includes obtaining a holographic image; determining at least one attenuation function due to motion blur from the holographic image; and correcting the holographic image, or a portion thereof, using the at least one attenuation function.
Abstract:
An apparatus for maintaining an optical gap between a pellicle and a reticle in a photolithography system includes a frame defining first and second opposing surfaces, a reticle mated to the first opposing surface using magnetic coupling; and a pellicle mated to the second opposing surface using magnetic coupling.
