“…The traceable calibration of an Imaging Luminance Measurement Device (ILMD) or of the luminance distribution of a light source requires knowledge about numerous contributions to measurement errors and uncertainties. Typically, a light source with a uniform luminance is used to characterize the relative non-uniformity of the photo-response (PRNU) (Bünger et al, 2015). In case of a non-uniform luminance, a sequence of translation can be used (Ferrero et al, 2014).…”

The traceable calibration of an Imaging Luminance Measurement Device (ILMD) requires a detailed characterization as well as an estimation of uncertainty contributions. Both are related to the spatial and angular characteristic, therefore a variable but precisely known positioning of the ILMD in front of a light source is needed. This is realized by extending a photometric bench facility by an articulated industrial robot dedicated for absolute positioning of an ILMD. Emphasis is given to make also the robot cell itself capable for photometric measurements. The working space of the installed system, aspects regarding differences to the common use of such industrial robots, and issues of an ILDM as a tool are discussed.

“…An electric signal is generated and a Digital Level (DL) is obtained for the corresponding pixel, ultimately forming an image. Several post-processing techniques may then be applied to improve the accuracy of the raw signal, for instance bad pixel replacement functions [42]. Software-based nonuniformity correction (NUC) corrected the non-uniform distribution of radiation being absorbed across the sensor due to the camera optics, which is discussed in Section 3.3.…”

High-Speed Infrared Measurement of Injector Tip Temperature during Diesel Engine Operation

Pre-catalyst engine emissions and detrimental injector deposits have been widely associated with the near-nozzle fluid dynamics during and after the injection events. Although the heating and evaporation of fuel films on the nozzle surface directly affects some of these processes, there are no experimental data for the transient evolution of nozzle surface temperature during typical engine conditions. In order to address this gap in knowledge, we present a non-intrusive approach for the full-cycle time resolved measurement of the surface temperature of production nozzles in an optical engine. A mid-wave infrared high-speed camera was calibrated against controlled conditions, both out of engine and in-engine to account for non-ideal in surface emissivity and optical transmissivity. A custom-modified injector with a thermocouple embedded below the nozzle surface was used to validate the approach under running engine conditions. Calibrated infrared thermography was then applied to characterise the nozzle temperature at 1200 frames per second, during motored and fired engine operation, thus revealing for the first time the effect of transient operating conditions on the temperature of the injector nozzle’s surface.

Abstract-In order to better detect the quality of aquatic products, a water quality and safety traceability system based on Internet of things has been designed. By analyzing the marine product quality and safety control, a standardized, intelligent and universal marine product quality safety traceability system is proposed based on the Internet of things technology and the characteristics of the seafood industry chain are analyzed. The process about "seedling purchase (seedling propagation) -seafood cultivation -seafood fishing -seafood processing -seafood sales" is selected as the main line, and sensors are used to collect seafood information. The final information is pooled into the seafood traceability data center. Companies can view the seafood traceability data in the traceability system, and consumers can obtain product traceability data by scanning the two-dimensional code of product packaging. The system adopts B/S model and SSH framework to complete system development. The experimental results show that the new system provides powerful technical support for marine product traceability and marine product quality safety management. Based on the above finding, it is concluded that the traceability system has been technically able to effectively improve the product management of marine fishery enterprises through the information management technology. At the same time, it lays a good foundation for the overall upgrading and reform of China's marine fishery industry.
