“…The reason of this behavior is that if the image is corrected to increase the response in the corners where the irradiance is lower, the noise in these sections will also be increased so that the NETD value remains constant. The NETD degradation caused by the optical effects in IRCAM has been evaluated using theoretical models [20] and laboratory images showing similar results. These results indicate that the NETD value in the corners of the image, the less favorable sections of the detector, is lower than 150% of the NETD value in the central part of the image.…”

JEM-EUSO is a space observatory that will be attached to the Japanese module of the International Space Station (ISS) to observe the UV photon tracks produced by Ultra High Energy Cosmic Rays (UHECR) interacting with atmospheric nuclei. The observatory comprises an Atmospheric Monitoring System (AMS) to gather data about the status of the atmosphere, including an infrared camera (IRCAM) for cloud coverage and cloud top height detection. This paper describes the design and characterization tests of IRCAM, which is the responsibility of the Spanish JEM-EUSO Consortium. The core of IRCAM is a 640x480 microbolometer array, the ULIS 04171, sensitive to radiation in the range 7 to 14 microns.The microbolometer array has been tested using the Front End Electronics Prototype (FEEP). This custom designed electronics corresponds to the Breadboard Model, a design built to verify the camera requirements in the laboratory. The FEEP controls the configuration of the microbolometer, digitizes the detector output, sends data to the Instrument Control Unit (ICU), and controls the microbolometer temperature to a 10 mK stability. Furthermore, the FEEP allows IRCAM to preprocess images by the addition of a powerful FPGA. This prototype has been characterized in the laboratories of Instituto de Astrofisica de Canarias (IAC). Main results, including detector response as a function of the scene temperature, NETD and Non-Uniformity Correction (NUC) are shown. Results about thermal resolution meet the system requirements with a NETD lower than 1K including the narrow band filters which allow us to retrieve the clouds temperature using stereovision algorithms.

“…Oznacza to, że materiał SBIR-S cechuje duża dyspersyjność powierzchni. Właściwość ta implikuje, że powierzchnia wykonana z materiału SBIR-S dobrze przybliża teoretyczną powierzchnię Lamberta, która rozprasza promieniowanie równomiernie w półsferę [6]. Powierzchnie o wysokiej emisyjności i wysokich wartościach dyfuzji są najbardziej odpowiednie do zastosowania jako powierzchnia wzorcowa dla promieniowania w podczerwieni lub w konstrukcji technicznego ciała doskonale czarnego.…”

Black body radiation sources are commonly used devices in areas related to thermal imaging and radiometry. They are the closest physical approximation of theoretical black body emitter derived from the Planck’s law. Majority of such devices are costly with restricted information about their production technology, including their emitter surface. A few relatively easily accessible coatings with potential application in such devices have been chosen and their emissivity measured. The paper presents measurements that provides information necessary to determine whether there are coatings viable for black body emitter or reference surface.
