Abstract
The disclosed display device for simulators has an off-axis collimated display system: a spherical screen and a spherical mirror that are fixed to a helmet worn by the user. This device gives a wide horizontal field and a relatively low attenuation of the external view.
Claims15
A device for the display of simulated images for helmets, comprising at least one device for collimation at infinity with a spherical mirror and a spherical screen fixedly joined to a helmet worn by the user, associated with a remote projector connected, firstly, by an optic fiber to an optic relay device fixed to the helmet and, secondly, to an image generator, the image generator being connected to a device for sensing the position of the head of the helmet wearer.
A device for a helmet for the display of simulated images, comprising:
- an image generator for generating a simulated image;
- a projector connected to said image generator for receiving the simulated image and for projecting the simulated image;
- an optic fiber connected to said projector for transmitting said simulated image;
- an optic relay device connected to the helmet for receiving the simulated image from the topic fiber;
- at lest one optic image-formation device connected to said optic relay device for collimation at infinity of said simulated image, each optic image-formation device comprising a spherical mirror and a spherical screen joined to the helmet;
- and
- sensing means for sensing the position of the helmet, said sensing means being connected to said image generator.
