DEVICE AND METHOD FOR DETECTING NON-VISIBLE CONTENT IN A NON-CONTACT MANNER
First Claim
1. A device for detecting non-visible content of an object in a non-contact manner, the device comprising:
- a light source configured to emit light toward a surface of an object over a period of time;
an optical sensing component configured to receive a pattern of light from the surface of the object, and to record the received pattern at plural points in time; and
a processing component configured to determine temporal changes in the pattern during the plural points in time, and to detect whether motion is present in the object based on determined temporal changes in the pattern, the motion representing a frequency source of non-visible content in the object.

Abstract
A method and device are provided for detecting non-visible content of an object in a non-contact manner. The device includes a light source configured to emit light toward a surface of an object over a period of time. The device also includes an optical sensing component configured to receive a pattern of light from the surface of the object, and to record the received pattern at plural points in time. In addition, the device includes a processing component configured to determine temporal changes in the pattern during the plural points in time, and to detect whether motion is present in the object based on determined temporal changes in the pattern, where the motion represents a frequency source of non-visible content in the object.

26. A method for detecting non-visible content of an object in a non-contact manner, the method comprising:
-
emitting light from a light source toward a surface of an object over a period of time; receiving, by an optical sensing component, a pattern of light from the surface of the object, and to record the received pattern at plural points in time; and determining, by a processor of a computer processing device, temporal changes in the pattern during the plural points in time; and detecting, by the processor, whether motion is present in the object based on determined temporal changes in the pattern, the motion representing a frequency source of non-visible content in the object. - View Dependent Claims (27, 28)

29. A non-transitory computer-readable recording medium having a computer program tangibly recorded thereon that, when executed by a processor of a computer processing device, causes the processor to carry out operations for detecting non-visible content of an object in a non-contact manner, the operations comprising:
-
emitting light toward a surface of an object over a period of time; receiving a pattern of light from the surface of the object, and to record the received pattern at plural points in time; and determining temporal changes in the pattern during the plural points in time; and detecting whether motion is present in the object based on determined temporal changes in the pattern, the motion representing a frequency source of non-visible content in the object.

30. A device for detecting non-visible content of an object in a non-contact manner, the device comprising:
-
a light source configured to emit light toward a surface of an object over a period of time; an optical sensing component configured to receive a pattern of light from the surface of the object, and to record the received pattern at plural points in time; and a processing component configured to define the pattern recorded at at least one of the plural points in time as a reference pattern, to determine temporal changes in the pattern during the plural points in time by comparing the pattern during the plural points in time with the reference pattern, and to detect whether motion is present in the object when determined temporal changes in the pattern differ a predetermined amount the reference pattern, the motion representing non-visible content in the object.
