Abstract
Abstract A device mounted in a craft for recording data from a remote object, such a scanner or panoramic camera. The main axis of the device is mounted perpendicular to the direction of movement of the craft and the device includes one plane mirror in front of and one plane mirror behind a primary element such as a prism or a mirror rotating about the main axis and oriented at a fixed angle of 45° to the main axis.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
In a device arranged to record data from a remote object constituted by a surface while being moved in a given direction relative to such surface, the device including a primary element mounted for continuous rotation about a main axis and presenting a radiation reflecting surface oriented at a fixed angle of 45 degrees to the main axis and the main axis being substantially perpendicular to the surface, the improvement wherein said device further comprises a first plane mirror permanently disposed on one side of said main axis a second plane mirror permanently disposed on the opposite side of said main axis, at least one of said mirrors being oriented so that its reflecting surface extends at an angle unequal to 45° to the main axis, and two pivotally mounted mirror support shafts each carrying a respective one of said plane mirrors and each lying in a plane which is perpendicular to the main axis.
Claim 2
Dependent Claim
155 words
In a device arranged to record data from a remote object constituted by a surface while being moved in a given direction relative to such surface, the device including a primary element mounted for continuous rotation about a main axis and presenting a radiation reflecting surface oriented at a fixed angle of 45 degrees to the main axis and the main axis being substantially perpendicular to the surface, the improvement wherein said device further comprises a first plane mirror permanently disposed on one side of said main axis a second plane mirror permanently disposed on the opposite side of said main axis, at least one of said mirrors being oriented so that its reflecting surface extends at an angle unequal to 45° to the main axis, and two pivotally mounted mirror support shafts each carrying a respective one of said plane mirrors and each lying in a plane which is perpendicular to the main axis.
Claim 3
Dependent Claim
20 words
A device according to claim 1, wherein both said mirrors form equal but oppositely directed angles to the main axis.
Claim 4
Dependent Claim
51 words
A device according to claim 1, wherein said shafts are further mounted to be movable in said plane to give said mirrors an orientation which establishes a correlation with the ratio between the rotational speed of said primary element and the speed of said device in the direction of its movement.
