Time-of-flight camera
A time-of-flight camera (ToF camera) is a range imaging camera system that resolves distance based on the known speed of light, measuring the time-of-flight of a light signal between the camera and the subject for each point of the image. The time-of-flight camera is a class of scannerless LIDAR, in which the entire scene is captured with each laser or light pulse, as opposed to point-by-point with a laser beam such as in scanning LIDAR systems.〔
Time-of-flight camera products for civil applications began to emerge around 2000, as the semiconductor processes became fast enough for such devices. The systems cover ranges of a few centimeters up to several kilometers.〔http://ssco.gsfc.nasa.gov/workshop_2010/day3/Roger_Stettner/Stettner_ASC_Workshop_Presentation.pdf〕 The distance resolution is about 1 cm. The lateral resolution of time-of-flight cameras is generally low compared to standard 2D video cameras, with most commercially available devices at 320 × 240 pixels or less as of 2011. Compared to 3D laser scanning methods for capturing 3D images, TOF cameras operate very quickly, providing up to 160 images per second.〔http://ww2.bluetechnix.com/en/products/depthsensing/list/argos/〕
==Types of devices==
Several different technologies for time-of-flight cameras have been developed.
