International Classification:

A61B 5/00
G01J 1/42
G01N 21/00

US Classification:

600365, 250393, 356436, 356 39

Abstract:

Systems and methods for non-invasively scanning and analyzing one or more characteristics of a sample utilizing electromagnetic radiation are described. More particularly, the systems and methods utilize an electromagnetic radiation source connected to a transmitter and an analyzer connected to a receiver. A sample to be analyzed is placed between the transmitter and receiver in a variety of different manners and a frequency sweep of electromagnetic radiation is transmitted through the sample to create a series of spectral data sets that are used to create one or more composite spectrograms, which are then analyzed to determine one or more characteristics of the sample. A magnetic field can alternatively be applied around the transmitter, receiver and sample to enhance some characteristic analysis applications. Samples include inert and living items, and the characteristics include a wide variety of different applications.

Abstract:

An n-port network analyzer system is calibrated. An initial calibration is performed for each test port in the network analyzer system by first performing a measurement calibration using calibration standards. The calibration standards are located in a reference plane located outside the network analyzer system. The measurement calibration yields initial calibration coefficients. The initial calibration coefficients include Forward Load Match (LM ) and Reverse Load Match (LM ). Electronic standards are measured within the network analyzer system to: produce initial measured electronic standards. The initial calibration coefficients and the initial measured electronic standards are used to generate initial corrected electronic standards. After the initial calibration, automatic re-calibrations are performed periodically. When performing the automatic recalibration, the electronic standards within the network analyzer system are measured to produce recalibration measured electronic standards.
