Method and device for detecting an object in a substrate

摘要

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.

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.
