摘要： Apparatus for creating an image indicating distances to objects in a scene, comprising: a modulated source of radiation, having a first modulation function, which directs radiation toward a scene; a detector, which detects radiation reflected from the scene, modulated by a second modulation function, and generates, responsive to said detected modulated radiation, signals responsive to the distance to regions of the scene; a processor, which receives signals from the detector and forms an image, based on the signals, having an intensity value distribution indicative of the distance of objects from the apparatus; and a controller, which varies at least one of the first and second modulation functions, responsive to the intensity value distribution of the image formed by the processor.

摘要： Apparatus for creating an image indicating distances to objects in a scene, comprising: a modulated source of radiation, which directs radiation toward a scene; telecentric optics, which receive and collimate radiation reflected from the scene; a modulator, which modulates the collimated radiation; a detector which detects an image formed from the modulated collimated radiation; and a processor, which forms an image having an intensity value distribution indicative of the distance of objects from the apparatus, responsive to the intensity distribution of the detected image.

摘要： Apparatus for creating an image indicating distances to objects in a scene, comprising: a modulated source of radiation (40), having a first modulation function (60), which directs radiation toward a scene; a detector (22), which detects radiation reflected from the scene, modulated by a second modulation function (62), and generates, responsive to said detected modulated radiation, signals responsive to the distance to regions of the scene; a processor (24), which receives signals from the detector and forms an image, based on the signals, having an intensity value distribution indicative of the distance of objects from the apparatus; and a controller (46), which varies at least one of the first and second modulation functions, responsive to the intensity value distribution of the image formed by the processor.
