    Abstract: A bidirectional reflectance distribution function (BRDF) measurement system and method, an electronic device, and a storage medium. The BRDF measurement system includes: a blackbody, a spectroradiometer and a controller; where in case that the blackbody is heated to a target temperature, it undergoes a solid-liquid phase change; the spectroradiometer is used to measure the blackbody and transmit a first measurement signal to the controller, and in case that the blackbody irradiates a to-be-measured point on a sample surface, the spectroradiometer is further used to measure radiation from the to-be-measured point, and transmit a second measurement signal to the controller; and the controller is used to obtain a BRDF of the to-be-measured point based on the first measurement signal, the second measurement signal, the target geometric relationship, a target mapping relationship and a dimension parameter of the blackbody.

    Abstract: A high SNR in-situ measurement of sample radiance in a low-temperature ambient environment is used to accurately characterize sample emissivity for transmissive, low-emissivity samples. A low-e mirror is positioned behind the sample such that the sample and low-e mirror overfill the field-of-view (FOV) of the radiometer. The sample is heated via thermal conduction in an open environment. Thermal conduction heats the sample without raising the background radiance appreciably. The low-e mirror presents both a low emission background against which to measure the sample radiance and reflects radiance from the back of the sample approximately doubling the measured signal. The low-e mirror exhibits a reflectance of at least 90% and preferably greater than 98% and an emissivity of at most 7.5% and preferably less than 2% over the spectral and temperature ranges at which the sample emissivity is characterized.

    Abstract: A geometrically shaped photonic crystal structure consisting of alternating layers of thin films is heated to emit light. The structure may include index matching layers or a cavity layer to enhance emissions. The layer thicknesses of the structure may be spatially varied to modify the emission spectrum versus emission angle. The self-focusing structure may be fabricated into a convex electrically heated wire filament light bulb, a concave visible thermophotovoltaic emitter, a concentric directional heat exchanger, an electronic display, or a variety of irregularly shaped remotely read temperature or strain sensors.

    Abstract: Silicon Carbide (SiC) probe designs for extreme temperature and pressure sensing uses a single crystal SiC optical chip encased in a sintered SiC material probe. The SiC chip may be protected for high temperature only use or exposed for both temperature and pressure sensing. Hybrid signal processing techniques allow fault-tolerant extreme temperature sensing. Wavelength peak-to-peak (or null-to-null) collective spectrum spread measurement to detect wavelength peak/null shift measurement forms a coarse-fine temperature measurement using broadband spectrum monitoring. The SiC probe frontend acts as a stable emissivity Black-body radiator and monitoring the shift in radiation spectrum enables a pyrometer. This application combines all-SiC pyrometry with thick SiC etalon laser interferometry within a free-spectral range to form a coarse-fine temperature measurement sensor. RF notch filtering techniques improve the sensitivity of the temperature measurement where fine spectral shift or spectrum measurements are needed to deduce temperature.

    Abstract: An infrared thermometer includes a probe and an infrared sensor. The probe with an infrared target absorbs thermal radiation to provide a substantially consistent source of infrared radiation and an aperture for preventing contamination of the infrared target while permitting the transmission of thermal radiation to the target. The infrared sensor is configured for sensing infrared radiation from the infrared target. The infrared target is positioned within the probe such that it absorbs thermal radiation that comes from the aperture and thereafter emits thermal radiation to the infrared sensor.
