Abstract
Disclosed is a method and apparatus for reproducing remotely sensed images in which the effect of attitude perturbation in the sensing device is removed from the image. The image is acquired by means of an electromagnetic radiation sensor mounted on a non-stationary body, such as an earth satellite, a helicopter, or the shoulder of a cameraman. An electronic signal representative of the three-axis attitude perturbation of the sensor is generated simultaneously with the data signal from sensor and a signal representative of the instantaneous nominal attitude thereof. These signals are transmitted (in some cases with the intermediate step of tape recording) to an image reproduction device such as a cathode ray tube or a portion of photographic film exposed by a narrow-beam light source. The data signal activates the image generator (i.e., the electron beam or the exposing light source); the signal corresponding to the nominal sensor attitude scans the image generator (e.g., by plate or coil deflection in the cathode ray tube or by beam deflection in the photographic image reproduction system); and the three-axis attitude perturbation signals perturb the image generator motion in the same manner as the sensor itself is perturbed while sensing the original image.
