Abstract
An image generating device is disclosed having a light source configured to produce an upstream light beam, and an array of elements with variable transmittance configured to selectively receive and transmit the upstream light beam so as to form a downstream light beam forming an image. A downstream face of the array of variable transmittance elements is in contact with an at least partially transparent plate configured to limit heating of the array of variable transmittance elements. A downstream face of the partially transparent plate is in contact with a cold face of a thermoelectric cooling module.
Claims12
An image generation device comprising:
- a light source configured to produce an upstream light beam;
- and
- an array of elements with variable transmittance,
- wherein the array of elements positioned between a first upstream polarizer forming an upstream side of the array of elements with variable transmittance, and a second downstream polarizer forming a downstream side of the array of elements with variable transmittance is configured to selectively receive and transmit the upstream light beam so as to form a downstream light beam forming an image,
- wherein the downstream side of the array of elements with variable transmittance, formed by the second downstream polarizer, is in contact with an upstream side of an at least partially transparent plate configured to limit heating of the array of elements with variable transmittance, and
- wherein a downstream side of the partially transparent plate is in contact with a cold side of a thermoelectric cooling module.
