1. A method for detecting an object in a substrate, comprising the steps of:
- transmitting a transmission signal by a first sensor element of a sensor unit;
receiving a first receive signal by the first sensor element of the sensor unit;
simultaneously with receiving the first receive signal, receiving a second receive signal by a second sensor element of the sensor unit;
simultaneously calculating a first depth cross-sectional image from the first receive signal and a second depth cross-sectional image from the second receive signal by a control and evaluation unit; and
displaying at least one of the first depth cross-sectional image and the second depth cross-sectional image on a display unit.

Abstract
A method and device for detecting an object in a substrate is disclosed. The device has a sensor unit having a sensor element and at least one further sensor element, a control and evaluation unit, and a display unit. The method for detecting an object in a substrate includes simultaneous reception of a receive signal and at least one further receive signal and simultaneous calculation of a depth cross-sectional image from the receive signal and at least one further depth cross-sectional image from the at least one further receive signal by the control and evaluation unit.

10. A device for detecting an object in a substrate, comprising:
-
a sensor unit having a first sensor element and a second sensor element, wherein a transmission signal is transmittable by the first sensor element and wherein a first receive signal is receivable at the first sensor element and a second receive signal is simultaneously receivable at the second sensor element; a control and evaluation unit, wherein the sensor unit is controllable by the control and evaluation unit and wherein respective depth cross-sectional images are simultaneously calculatable by the control and evaluation unit from the first receive signal received at the first sensor element and from the second receive signal received at the second sensor element; and a display unit, wherein the respective depth cross-sectional images are displayable on the display unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
