摘要： A cigarette temperature detection device including multiple cylindrical convex lenses is provided, wherein each of the cylindrical convex lenses has a thicker central wall between two thinner end walls formed by rotating a parallel line at a predetermined distance around a long axis of an elliptical-like section resulting from cutting the circular convex lens by a plane perpendicular to a centerline. The disclosed cigarette temperature detection device allows accurate and reliable detection of a temperature of an entire circumferential surface of a cigarette on site.

摘要： An optical device is provided. The optical device includes a time-of-flight (TOF) sensor array, a photon conversion thin film, and a light source. The photon conversion thin film is disposed above the time-of-flight sensor array. The light source emits light with a first wavelength towards the photon conversion thin film to be converted into light with a second wavelength received by the time-of-flight sensor array. The second wavelength is longer than the first wavelength.

摘要： The present disclosure relates to a system for sensing temperature changes on a microsecond scale. The system uses a multi-channel pyrometer that works in the NIR spectrum to receive thermal radiation. Each channel includes an interference filter tuned to pass thermal radiation within a specified wavelength range, and a detector. Each detector detects thermal radiation focused on it. Each channel further includes an interference filter which reflects thermal radiation which does not pass through it to a subsequent downstream interference filter of a subsequent channel. Each subsequent interference filter is oriented to reflect the thermal radiation not passing through it to a next downstream one of the subsequent interference filters. A subsystem is included for receiving the output from the detectors and determining sensed temperature data therefrom, allowing measurement of temperatures down to 800 K.

摘要： A method of forming an infrared detector includes defining an optical window in a cover substrate. Defining the optical window includes forming a multilayer interference filter or a periodic diffraction grating on an upper surface of the optical window and a periodic diffraction grating on the lower surface of the optical window. The method also includes performing anodic bonding of a spacer onto the cover substrate, transferring the cover substrate provided onto a base substrate, and hermetically bonding the spacer onto the base substrate.
