ICWS Periscope

摘要

A periscope construction having a ballistic guard formed inside a protective housing, and optical system mounted therein having first and second blocks of optical material mounted at opposite ends; first and second reflective surfaces, and the object and eyepiece viewing surfaces of the respective blocks being generally parallel and forming a parallelogram in cross section; the first and second end surfaces being spaced from each other within the housing with at least one layer of transparent armor therebetween to deflect incoming projectiles away from the object viewing section; and may include at least one layer of transparent armor rigidly positioned at an angle relative to the field of view no less than 300° to a maximum of 360° which is parallel to the field of view. It may further include a high grade metallic band rigidly formed around and adjacent the space between the first and second end surfaces.

主权项

1. A periscope construction of the type having a protective housing and an optical system mounted within the housing, in which the optical system comprises:
(a) a first block of optical material forming an object viewing section having an object viewing surface, a first reflective surface and a first end surface; (b) a second block of optical material forming an eyepiece viewing section having an eyepiece viewing surface, a second reflective surface, and a second end surface; (c) said first and second blocks being mounted at generally opposite ends of the protective housing with the first and second reflective surfaces, and the object and eyepiece viewing surfaces being generally parallel with respect to each other and forming a parallelogram in cross section, and with the first and second end surfaces being spaced from each other within the protective housing with at least one layer of transparent armor filling the space therebetween parallel to the field of view to deflect incoming projectiles from striking the object viewing section.
