Abstract
Different examples relate to techniques in order to actively or passively stabilize the temperature of a holographic optical element. To this end, heat-conducting elements, e.g. silver nanowires or carbon nanotubes, are provided.
Claims15
A system, comprising:
- at least one substrate,
- at least one first layer applied on the at least one substrate, wherein each of the at least one first layer comprises a respective holographic optical element, and
- at least one second layer applied on the at least one substrate, wherein each of the at least one second layer comprises at least one respective heat-conducting element.
A method for temperature stabilization of one or more holographic optical elements, wherein the one or more holographic optical elements are embodied in at least one layer, wherein an electrical heating element is arranged in a manner adjoining the at least one layer,
- wherein the method comprises:
- adjusting a current flow of a current source through the electrical heating element on the basis of a temperature measurement value of a temperature sensor arranged in a vicinity of the at least one layer,
- wherein the current flow is furthermore adjusted on the basis of a target temperature.
