The Embedded Image Periscope (EIP) designed and patented by Kent Periscopes provides standard unity vision periscope functionality for normal daytime viewing of the vehicle surroundings plus the ability to display digital images from a range of on-vehicle sensors and cameras (including thermal and low light) such that the resulting image appears "embedded" internally within the unit and projected at a comfortable viewing positions. Now,when the reflection is created on the first mirror a lateral inversion happens. When a ray reflected by the first plane mirror shifts the incident ray for the second one, this laterally inverted incident ray gets reflected by the second plane mirror and reaches the eyes as an image of an object without lateral inversion. 1. (2) The image formed in a plane mirror is at the same distance behind the mirror as the object is in front of it. The image formed is real . More complex periscopes use prisms instead of mirrors to provide magnification and higher image quality.
