Abstract
Apparatus for creating an image indicating distances to points in objects in a scene, comprising: PA1 a modulated source of radiation, having a first modulation function, which directs radiation toward a scene such that a portion of the modulated radiation is reflected from the points and reaches the apparatus; PA1 an array detector which detects radiation from the scene, modulated by a second modulation function, each element of the array detector being associated with a point in the scene, each element of the array detector generating a signal, responsive to a part of the reflected radiation reaching the apparatus, the magnitude of particular element's signal being dependent on the distance of a point in the scene, associated with that element's signal; and PA1 a processor which forms an image, having an intensity value distribution indicative of the distance of each of the points in the scene from the apparatus, based on the magnitude of the signal associated with the point; PA1 wherein the first and second modulation functions comprise repetitive pulsed modulation functions which are different from each other.
