摘要： Apparatus and methods are disclosed for highly accurate remote measurement of sea surface skin temperature. Thermal band 8 to 14 micron images of the surface of the ocean taken by a downward looking infrared camera are processed to determine the optimum segments of the image to utilize. The influence of contaminating reflection of the downwelling flux from the sky and other error sources are removed and from the data and/or otherwise corrected for making sea surface temperature accuracy within several tenths of a degree possible.

摘要： An infrared imaging system is provided. The system includes a sensor configured to receive light emitted by a scene and at least a portion of scenic flux to generate image data, a light source configured to provide calibrating light to offset at least a portion of the scene flux, the light source positioned such that an output of the light source is at a pupil of the infrared imaging system, and at least one image processing device. The image processing device is configured to receive the image data generated by the infrared sensor, determine at least one change in the scenic flux as received by the infrared sensor, determine if the at least one change in the scenic flux results in a change in pixel response of the infrared sensor that exceeds a response threshold, and if the change in pixel response exceeds a threshold, generate an updated calibration table.

摘要： A method of measuring temperature based upon a system of equations applying Stefan-Boltzmann's law and using a measurement value for an object to be measured and an ambient temperature value (Ta) comprises: pre-calculating (200, 202) a first vector (LUT1) and a second vector (LUT2). The first vector (LUT1) is a series of values proportional to received power based upon respective temperature values and in respect of a predetermined generic range of temperatures. The second vector (LUT2) is a series of sensitivity characteristic factor values based upon expected measured temperature values and in respect of a predetermined range of expected object measured temperatures. The first vector (LUT1) and the second vector (LUT2) are used (206) to generate a temporary vector (LUTT) of a series of values limited to the ambient temperature value to solve the system of equations in respect of the measurement value for the object, thereby determining (208) a temperature (To) for the object from the measurement value.

摘要： The present invention discloses a method for measuring an actual temperature of a flame by using all information of a radiation spectrum and a measurement system thereof. The method includes: conducting more theoretical data processing by using energy level structure correction, wherein all information of the radiation spectrum can be used; and by way of a keyboard input manner or a data transmission input manner, acquiring an energy level structure correction parameter, and finally acquiring a more accurate actual temperature value of a measured flame. The method effectively overcomes a defect that the true temperature of the flame can be obtained by only conducting radiance correction through data processing with great calculations when adpted multi-spectral temperature measurement method. In the existing multi-spectral temperature measurement method at present, only information of several monochromatic radiation capacities in the radiation spectrum can be used; and in the method, information of all the monochromatic radiation capacities, thousands of monochromatic radiation capacities in general, in the radiation spectrum can be used.

摘要： Disclosed is an error correction unit enabling constant accurate measurement of a moving object by correcting an error attributable to a change in sensitivity of a thermal image sensor, a change in distance between a thermal image sensor and an object, or an ambient environment. Further disclosed is an object temperature detection device equipped with the same. The error correction unit includes a first arm member rotatably coupled to a thermal imaging camera unit, a heating element holder rotatably coupled to the first arm member, the heating element fixed to the heating element holder, and a temperature sensor configured to measure a temperature of the heating element. The heating element is positioned within an angle of view of the thermal imaging camera unit through rotational motion of the first arm member and the heating element holder. The temperature sensor measures the temperature of the heating element at a first time and a second time different from the first time so that the controller can use a temperature change value of the heating element. Data of the temperatures of the heating element, which are measured respectively at the first time and the second time, are transmitted to the controller.

摘要： A device and method of use for the calibration of a detector. The calibration device includes a first source configured to produce first electromagnetic energy EMR. A first diffuser is connected to the first source and is configured to accept the first EMR and provide a first diffused portion of the first EMR. An integrating sphere defines an interior and is optically connected to the first diffuser, and is configured to accept the first diffused portion from the first diffuser into the interior. An exit port connected to the integrating sphere is configured to pass at least a portion of electromagnetic energy. A thermal mechanism is configured to adjust and maintain the temperature of at least the first source. The integrating sphere is configured to pass only a second portion of the first diffused portion of the first EMR from the first diffuser to the exit port. In another embodiment, the calibration device has an arm, an actuator, and a module. The module supports at least a first source that emits electromagnetic energy, a thermal mechanism, and a controller. The actuator is configured to move the arm and module to a calibration position enabling the first source to be within the line of sight of an external detector, while the controller is configured to control the thermal mechanism enabling precise temperature regulation of the source and therefore the regulation of the emitted electromagnetic energy. When the device is not in the calibration position, the actuator is configured to move the arm and module to a stowed position, protecting the device from ambient electromagnetic radiation and harm.
