A telemetry system comprises a video camera of the kind such that, as a result of the substantial magnification provided, it is necessary also to use a collimating video camera. The use of the collimating camera is rendered possible by mirrors which enable the telemetry operation to be carried out on a virtual object. The system is of especial value in installations which are hostile and inaccessible to human beings.

In a collimating telemetry optical system for finding the distance of a viewed image comprising: two first mirrors each rotatable about an axis lying parallel to the axis of the other, synchronized in rotation to each other, and each lying in a respective, different optical path from an object to superposed images of the object, the two optical paths being of the same length, the said image defining with a reference point a first optical axis, and two second, co-planar, mirrors each located on a respective one of said optical paths and symmetrically with respect to the first optical axis, the arrangement being such that the telemetry is carried out on a virtual object, an image thus produced defining with the virtual object a second optical axis and wherein the plane constituted by said second mirrors is perpendicular to the plane constituted by said first and second optical axis.
