Abstract

An optical module for an independent line of sight is capable of being arranged on a sight unit. The optical module contains at least a first mirror and at least a movably arranged second mirror. A method for converting an existing weapon station into a weapon station with an independent line of sight, a sight unit arranged with an optical module, and a weapon station embodied with a sight unit, wherein an optical module is arranged on the sight unit, are also provided.

First claim

The invention claimed is:

1. An optical module for an independent line of sight, in relation to a second line, wherein the optical module is capable of being arranged on a sight unit, the optical module comprising at least a first mirror and at least a movably arranged second mirror, wherein it is possible to select, by moving the first mirror;
i) wherein the optical module provides an independent line of sight, when the optical path passes via a second entry point arranged on the optical module, via at least the movably arranged second mirror and the first mirror, to an exit point arranged on the optical module, or
ii) wherein the optical module does not influence the optical path through the optical module, when the optical path passes freely through the optical module through a first entry point arranged on the optical module to the exit point arranged on the optical module, wherein the movably arranged second mirror is controlled from an externally arranged control unit.

2. The optical module according to claim 1 , wherein the optical module is arranged with a movable hatch, wherein the movable hatch can be moved between covering the first entry point or covering the second entry point.

3. An optical module for an independent line of sight, in relation to a second line, wherein the optical module is capable of being arranged on a sight unit, the optical module comprising at least a first mirror and at least a movably arranged second mirror, wherein it is possible to select, by moving the first mirror;
i) wherein the optical module provides an independent line of sight, when the optical path passes via a second entry point arranged on the optical module, via at least the movably arranged second mirror and the first mirror, to an exit point arranged on the optical module, or ii) wherein the optical module does not influence the optical path through the optical module, when the optical path passes freely through the optical module through a first entry point arranged on the optical module to the exit point arranged on the optical module, wherein the optical module is arranged with a control unit comprising at least one gyro.

4. The optical module according to claim 3 , wherein the movably arranged second mirror is controlled from an externally arranged control unit.

5. A device for a sight, comprising the optical module according to claim 1 arranged on a sight unit for arrangement on a weapon station or a launching device.

6. The device according to claim 5 , wherein the sight unit contains electro-optical sensors.

7. Device according to claim 6 , wherein the electro-optical sensors are at least one of the following: a video sensor adapted for the visible optical wavelength range, an IR sensor or a laser rangefinder.

8. A weapon station embodied with the device according to claim 5 .

9. A method for converting an existing weapon station into a weapon station with an independent line of sight, wherein the conversion involves the arrangement of the optical module with a variable line of sight according to claim 1 , on a weapon station.
