ABSTRACT:
A system for photographically displaying the magnitude of a physical variable. In one embodiment, a sensor mounted on a movable probe produces an electrical signal indicative of the physical variable. The electrical signal then drives a lamp which is also mounted on the movable probe. A photographic time exposure of the lamp made while the probe scans an area provides a two-dimensional map of the physical variable. In another embodiment, a position transducer measures probe movement to provide an output indicative of the position of the sensor. The transducer output drives a positioning mechanism on which the lamp is mounted so that movement of the lamp corresponds to the movement of the sensor.
