摘要： A weak target detection-oriented multi-modal infrared imaging system includes an infrared optical window, a large-field of view (FOV) two-dimensional scanning mirror, a Cassegrain reflector group, a broadband spectrum relay mirror, a first lens group, a space-adjustable and transmittance-variable lens, a second lens group, a focal plane array (FPA) module, a data processing module and a space addressable transmittance modulation module. The data processing module generates a transmittance modulation control signal and an imaging integration time modulation signal according to an image data signal output by the FPA module, and the space-adjustable and transmittance-variable lens dynamically adjust an optical field transmittance under the effect of the transmittance modulation control signal. The FPA module adaptively adjusts an imaging integration time under the effect of the imaging integration time modulation signal.

摘要： Scanning apparatus operable in the microwave, mm-wave and infrared ranges and comprises a hollow polygonal primary drum which is mounted for rotation about a central axis. The primary drum provides a plurality of internally presented sides or facets, which are capable of reflecting the microwave, mm-wave and infrared radiation concerned. A fixed Mangin mirror mounted within the primary drum directs such radiation emanating from a view of view of the apparatus, onto the internally presented sides or facets of the primary drum, such that in each of a succession of line scanning periods, radiation emanating from the field of view is directed onto a reflective side or facet of the primary drum to be reflected therefrom onto a further receiving assembly comprising a rotating faceted reflector, in the form of a secondary drum. The secondary drum is arranged to reflect the radiation striking it from the first drum to focus onto a radiation receiver or sensor. The secondary drum is arranged to be rotated, about an axis parallel with the rotary axis of the primary drum, in synchronism with the latter, in such a way that, over each line scanning period, radiation from substantially all of the respective facet of the primary drum can reach said receiver or sensor via said secondary drum. The invention provides a simply constructed robust and yet relatively inexpensive apparatus for forming images in the radiation concerned.

摘要： An arrangement for calibration of at least one radiation-sensitive detector, comprising an aperture (90), at least one reference body (50, 60, 600) which emits radiation with a measurable intensity, at least one deflection member (160, 170, 620) which deflects radiation from the reference body, and at least one radiation-sensitive detector (30) which detects the radiation value and generates an output signal dependent on the detected radiation value. During reference measurement the deflection member is arranged to reproduce the aperture (90) on the reference body (50, 60, 600), and the deflection member (160, 170, 620) deflects the radiation such that the midpoint of the reproduction of the aperture (90) remains on substantially the same area of the surface of the reference body (50, 60, 600) during that time period in which the detector receives radiation which is transmitted from the reference body and which passes through the aperture (90).

摘要： A hand-held probe system for imaging is described which includes a hand-held probe and a detector assembly connected by a fiber optic cable. The probe includes a hand-portable housing, a detector assembly within the housing and an IR sensor placed on the cold finger of the detector assembly. The probe can include an optical system at a known distance from the sensor and a spacing tube defining the distance between the body and the optical system. The spacing tube ensures that the body whose thermal image is being read is always at, or is very close to, the object plane of the probe. The spacing tube is typically formed of a material having minimal thermal deformation which can minimize stray IR radiation.
