Abstract:
1. A vibration damping system, comprising: a first window structure; a second window structure that is spaced-apart from said first window structure by a first distance, in an arrangement by which said first and second window structures are substantially parallel to one another; wherein said first window structure comprises a first grouping of two separate layers of material that are both substantially transparent at visible optical wavelengths for humans, said first grouping of two separate layers being spaced-apart from one another by a second distance in an arrangement by which at least portions of said first grouping of two separate layers are substantially parallel to one another, thereby forming a first space between said first grouping of two separate layers of material of said first window structure in which said first space includes a first gaseous material; wherein said second window structure comprises a second grouping of two separate layers of material that are both substantially transparent at visible optical wavelengths for humans, said second grouping of two separate layers being spaced-apart from one another by a third distance in an arrangement by which at least portions of said second grouping of two separate layers are substantially parallel to one another, thereby forming a second space between said second grouping of two separate layers of material of said second window structure in which said second space includes a second gaseous material; wherein said second distance is less than said first distance, said third distance is less than said first distance, said second distance is of a size that provides air-film vibration damping for said first window structure; and said third distance is of a size that provides air-film vibration damping for said second window structure; and wherein at least one of said first and second window structures exhibits an opening that extends completely therethrough, used for pressure equalization.
