Assembly and method for wavelength referencing of variable frequency Fabry-Perot interferometers

摘要

The arrangement has an electromagnetic radiation detecting element (9) including a sensitive layer (1) and electrode/reflector layers (2). The sensitive layer is made of sensitive material for an electromagnetic radiation (11), and the electrode/reflector layers are electrically conducted and partially reflected and partially transparent to the electromagnetic radiation. The electrode/reflector layers are arranged in path of beam of the electromagnetic radiation prior and behind the sensitive layer. The sensitive layer is formed with a pyro electric material. An independent claim is also included for a method for wavelength referencing a variable frequency Fabry-Perot interferometer.
