  • Publication number: 20210373355
    Abstract: A light field volumetric device for displaying images or flows of fluctuating and stereoscopic 3D images. The device includes emitting means and a reflection system. The reflection system has first and second concave reflecting means. The first concave reflecting means comprises an aperture. An image generated by the device is perceivable by an observer, located at a distance with respect to the second concave reflecting means, when the observer looks towards the second concave reflecting means. A calculation unit is associated with the device and is configured to calculate the distance.

  • Patent number: 10197803
    Abstract: The invention describes augmented reality glasses (1) for medical applications configured to be worn by a user, comprising a frame (15) that supports a glasses lens (2a, 2b), wherein the frame (15) comprises an RGB lighting system comprising RGB-emitting devices (16a, 16b, 16c) configured to emit light beams (B1, B2, B3); first optical systems (17a, 17b, 17c) configured to collimate at least partially said beams (B1, B2, B3) into collimated beams (B1c; B2c; B3c); wherein the frame (15) further comprises a display (3) configured to be illuminated by the RGB lighting system (16) by means of the collimated beams (B1c; B2c; B3c); to receive first images (I) from a first processing unit (10); to emit the first images (I) as second images (IE1) towards the glasses lens (2a, 2b), wherein the lens (2a, 2b) is configured to reflect the second images (IE1) coming from the display (3) as images projected (IP) towards an internal zone (51) of the glasses corresponding to an eye position zone of the user who is wearing th

  • Patent number: 9726888
    Abstract: The invention describes augmented reality glasses comprising a frame which supports a glasses lens, wherein associated with the frame are a miniaturized display configured for emitting images in a predetermined direction, an optical system configured for receiving the images coming from the display and creating processed images, and reflection means configured for receiving the processed images and reflecting them towards the glasses lens, so as to project the processed image onto this lens, wherein this lens is configured for reflecting the projected image in a direction of the ocular axis.
