Abstract
In an illustrative embodiment, an ultrasonic receiver supplies the echo signals with a given dynamic range to an image recording device which manifests a non-linear luminance/control characteristic. An imaging apparatus with a signal transmission chain of such a type is to be produced with which, by simple means, the echo dynamic range can be adapted to the luminance range detectable by the eye. This is achieved in that there is connected between the ultrasonic receiver and the image recording device, a distortion member, particularly a linearization member, which distorts, in particular, linearizes, in accordance with a specifiable pattern, the non-linear luminance/actuating characteristic of the recording device, in dependence upon a predetermined optimum dynamic range of the echo signals.
