초록 ▼

An infra-red imaging system is operable selectively in wide and narrow field of view modes. Radiation from the object is imaged onto an infra-red CCD staring focal plane array (SFPA) which provides an output representing the image. In the narrow field of view mode, operative on detection of a particular target by target detection electronics, the image is not scanned but is made to follow any movement of the target, and the SFPA stares at the target to build up an image. In the wide field of view mode, the same SFPA is used to provide the image, but the image is scanned along a swath. Smearing of the image is minimized by driving the IRCCD array such that the image-bearing charge is passed down the array from element to element at a speed equal to the scanning speed, so that the output signal from the end element represents the intensity of radiation from a given portion of the object time-integrated by all the elements of the array in succession.

대표청구항 ▼

A method of imaging with selectively a wide or a narrow field of view, using the same two-dimensional array of detector elements for both, each element storing an electrical signal representative of the time-integrated intensity of the light incident on it, wherein, in a wide field of view mode of operation, the array is made to scan swathes of an object along respective columns of the array and periodically the stored electrical signals are shifted simultaneously in the direction of the scan from each element to its neighbour for continued time-integration, the stored electrical signal from the end element of each column of the array being provided as an output signal, the average speed at which the signals progress along the array being equal to the speed of the image scan whereby smearing of the image is minimised, each successive output signal of a column being representative of the intensity of radiation from a different portion of the object time-integrated by all the elements in succession, and wherein, in a narrow field of view mode, the array is held stationary relative to the image, the elements are made to perform a time integration over a stare period substantially greater than the period between successive simultaneous shifts in the wide field of view mode, and the stored signals are then read out from all the elements.
