Multi-mode sight
First Claim
Patent Images
1. A multi-mode sight consisting essentially of:
- an optical sight that provides a direct view image of an aiming point or reticle superimposed on a target scene;
a thermal imager that provides a monochromic thermal image of the target scene;
a single, superimposed direct view and thermal optical image path defined through the optical sight;
a single combiner in the single, superimposed direct view and thermal optical image path that passes the direct view image and reflects the thermal image such that the thermal image is superimposed onto the direct view image to form a superimposed thermal and direct view optical image of the target scene together with the aiming point or reticle; and
a night-vision device positioned at an exit pupil, wherein the night-vision device light-intensifies the superimposed thermal and direct view optical image of the target scene together with the aiming point or reticle for night-time use.

Abstract
A multi-mode sight includes an optical sight that provides a direct view image of an aiming point or reticle superimposed on a target scene. The optical sight includes a single optical path defined through the sight comprising a direct view and overlay path. A thermal imager provides a monochromic thermal image of the target scene. A single combiner is located in the optical path and passes the direct view image and reflects the thermal image to overlay the thermal image onto the direct view image for an operator to see as a superimposed thermal and direct view optical image of the target scene together with the aiming point or reticle.

4. A fused thermal and direct view multi-mode aiming sight configured to mount onto a weapon for use as a day/night/thermal sight, the multi-mode aiming sight consisting essentially of:
-
an optical sight that provides a direct view image of an aiming point or reticle superimposed on a target scene; a thermal imager that provides a monochromic thermal image of the target scene; a single, superimposed direct view and thermal optical image path defined through the optical sight; and a single combiner in the single, superimposed direct view and thermal optical image path that passes the direct view image and reflects the thermal image such that the thermal image is superimposed onto the direct view image to form a superimposed thermal and direct view optical image of the target scene together with the aiming point or reticle; and a night-vision device positioned at an exit pupil, wherein the night-vision device light-intensifies the superimposed thermal and direct view optical image of the target scene together with the aiming point or reticle for night-time use. - View Dependent Claims (5, 6)
