Abstract
The present invention relates to an aerosol-generating device that is configured for generating an inhalable aerosol by heating an aerosol-forming substrate. The device comprises a device housing for receiving the aerosol-forming substrate and a pyrometer for determining a temperature of a heated target surface within the device housing. The invention further relates to an aerosol-generating system comprising such an aerosol-generating device and an aerosol-generating article for use with the device including an aerosol-forming substrate.
Claims11
An aerosol-generating device configured for generating an aerosol by heating an aerosol-forming substrate, the device comprising a device housing for receiving the aerosol-forming substrate, and a pyrometer for determining a temperature of a heated target surface within the device housing, wherein the pyrometer is a dual-wavelength pyrometer or a multiple-wavelength pyrometer that is configured to measure thermal radiation at least at a first wavelength band and a second wavelength band, wherein the second wavelength band is broader than the first wavelength band, and wherein the pyrometer includes a detector comprising at least a first and a second sensor, wherein the first and the second sensor are arranged adjacent to each other side by side, and wherein the pyrometer comprises an optical system for collecting thermal radiation emitted from the heated target surface, wherein the optical system comprises a lens having a lens surface far side of the target surface which is a scattering surface.
