Patent number: 12038489Abstract: Systems and methods are described, and one method includes illuminating a target-of-interest (TI) with an RF energy configured to effect, over a time duration extending from a first time to a second time, an increase in a temperature of the TI. At a first detection time within the time duration, a first temperature NQR signal spectrum of the TI is detected, and a corresponding first temperature NQR spectrum data set is generates. At a second detection time, subsequent to the first detection time, a second temperature NQR signal spectrum of the TI is detected and corresponding second temperature NQR spectrum data set is output. Based at least in part on the first temperature NQR spectral dataset and the second temperature NQR spectral dataset, the TI is classified between including the SI and not including the SI.Type: GrantFiled: April 21, 2021Date of Patent: July 16, 2024Assignee: THE TRUSTEES OF PRINCETON UNIVERSITYInventors: Alexei Goun, Herschel Rabitz

Publication number: 20230194702Abstract: Systems and methods are described, and one system includes a three-dimensional (3D) geometric tracker connected to a multiband (MB) inverse synthetic aperture array radar (ISAR), and a classification/alarm logic. The MB ISAR includes spatially distributed radar transmitters (TXs) and receivers (RXs), a TX/RX allocation logic, and a tomographic (TM) image logic. The TX/RX allocation logic is configured to receive 3D tracking data from the 3D geometric tracker, indicating subject 3D position and 3D orientation and, in response, dynamically allocate TXs and RXs to maintain MB illumination of and maintain MB reception of multiple scatter angles from subjects. The TM image processor is configured to construct TM images from the scatter angles, using 3D tracking data, for input to the classification and alarm logic. Optionally, the TX/RX resource allocation logic is configured to receive situation feedback data, for feedback adjusting of allocation of TXs and RXs.Type: ApplicationFiled: April 21, 2021Publication date: June 22, 2023Applicant: The Trustees of Princeton UniversityInventors: Alexei Goun, Herschel RABITZ

Publication number: 20080169416Abstract: Apparatus for analysing molecules, including an ablation device 1,10 for releasing molecules from a sample, and a laser device 1,2,3 for illuminating released molecules with a shaped laser pulse thereby to ionize and/or dissociate the molecules. The ablation device or laser device has at least one component which is not shared by the other device. This enables the steps of ablation and ionization/dissociation to be separated. The ablation device may be means for generating an ion or neutral beam, or an unshaped laser pulse. The laser device may be a femtosecond shaped pulse laser. The ablation device may illuminate the sample with a beam and the laser device preferably produces a pulse shaped laser beam which is spaced part from the sample.Type: ApplicationFiled: January 17, 2007Publication date: July 17, 2008Applicant: PULSED INSTRUMENTS, INC.Inventors: Stephen Paul Thompson, Victor Parr, Herschel Rabitz
