Method and apparatus for inspecting an object, particularly a piece of luggage
First Claim
1. A method for inspecting an object, the method steps comprising:
- emitting radiation by a stationary radiation source;
transporting the object in a straight line through the radiation;
detecting the intensity levels of unabsorbed radiation by a detector arrangement;
processing the detected intensity levels of the unabsorbed radiation into an image of the object; and
rotating the object through an angle after a pass through the radiation by a rotating device in order to change the object'"'"'s transport position, and subsequently transporting the object in a straight line through the radiation again, producing another image.

Abstract
In a device and processes for inspecting an object (1), particularly a piece of luggage, in which radiation is emitted by a stationary radiation source (2) while the object (1) is transported in a straight line through the radiation with intensity levels of unabsorbed radiation being detected by a detector arrangement (3) and processed into an image of the object (1), the object (1) is rotated by a rotating device (8) through an angle after a pass through the radiation in order to change its transport position, and is subsequently transported through the radiation again with another image being produced. This facilitates improved inspection by reducing so-called “dark alarms.”

13. An apparatus for inspecting an object comprising:
-
a stationary radiation source;
a detector arrangement facing the radiation source;
a transport device that conveys in a straight line for transporting the object through radiation from the radiation source; and
an analysis unit with a computer that generates an image from intensity levels detected by the detector arrangement, and a screen that displays the generated image;
wherein the transport device has a rotating device for rotating the object after a pass through the radiation to change its transport position, and wherein the object is subsequently transported in a straight line through the radiation again. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
