Linear scanning system for THz imaging
Applied Optics, 2021A linear scanning system utilizing constant wave 280 GHz radiation has been developed and characterized. The system comprises a linear array of detectors based on a unique plasma wave approach in terahertz sensing, an impact ionization avalanche transit-time-diode signal generator coupled to a frequency multiplier and an optical system.

Linear scan register allocation
ACM Transactions on Programming Languages and Systems, 1999We describe a new algorithm for fast global register allocation called linear scan . This algorithm is not based on graph coloring, but allocates registers to variables in a single linear-time scan of the variables' live ranges. The linear scan algorithm is considerably faster than algorithms based on graph coloring,

Linear scan control of tunable lasers using a scanning Fabry-Perot
Applied Optics, 1979A simple technique is described for servo control of the scan rate and drift of tunable cw lasers based on peak position readout in a repetitively swept Fabry-Perot interferometer referenced to a stabilized laser.

Interpolation from Samples on a Linear Spiral Scan
IEEE Transactions on Medical Imaging, 1987An interpolation method useful for reconstructing an image from its Fourier plane samples on a linear spiral scan trajectory is presented. This kind of sampling arises in NMR imaging. We first present a theorem that enables exact interpolation from spiral samples to a Cartesian lattice.

Wide-Scanning Conformal Linear Phased Array
2020 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2020In this paper, a wide-scanning linear conformal phased array is presented. The antenna element is mainly composed of a dipole, a Marchand balun, a shorting-pin, two directors and frequency selective surface (FSS) structure. Besides, the proposed array is implemented using the 1×12 radiating elements that are mounted onto a curved wing surface ...

Scanned directivity of linear arrays
IEEE Transactions on Antennas and Propagation, 1971Expressions for directivity as a function of spacing, scan angle, and current distribution are presented for uniformly spaced linear arrays subject to the assumption that the element radiation intensity function of each radiator can be expressed in either of the following forms: (1 - \sin^{2} \theta \cos^{2} \Phi)^{P} or \sin^{2P} \theta \sin^{2Q} \Phi
