A microwave photon beam forming network architecture based on switch switching type optical adjustable true delay line and its phased array radar system. The architecture realizes delay difference adjustment of multiple optical signals by modulating microwave signals in the optical domain and utilizing the characteristics of multiple adjustable delay paths in a single channel switch switching type delay line, thereby supporting high precision, wideband beam forming without beam oblique view while greatly reducing the number of delay lines and delay units; through two or more levels of delay configuration, the network can flexibly meet the wideband delay compensation requirements of different array antenna units, has relatively low complexity and strong dynamic reconfigurable ability, is suitable for implementation of large-scale photon integrated chips, the number of delay lines of the application is reduced by about 50%, and no frequency dispersion is generated, which can significantly reduce the system complexity, cost and power consumption, and is especially suitable for wideband phased array systems such as millimeter wave, satellite communication and radar detection.

The application relates to the technical field of semiconductor device special equipment manufacturing, and discloses a micro-order regulation method and system based on a metastable energy window. The method emits a pulse photon beam with a specific frequency to the surface of a semiconductor target material, so that lattice atoms enter a metastable energy window; the reflection spectrum of the semiconductor target material is collected in real time during the pulse intermittent period, and lattice vibration mode features are extracted; the lattice vibration mode features are compared with preset metastable energy window boundary threshold values, the photon density and the duration of the next pulse photon beam are dynamically adjusted according to the comparison result, and lattice atoms are repaired by short-range atomic rearrangement in the metastable energy window. The scheme limits energy injection to the metastable interval, and blocks the long-range diffusion path of doped atoms.

An assembly for scanning a core or rock sample is disclosed. The assembly includes a first high energy photon emitter that is configured to emit a first beam of photons at a first location on the core or rock sample and a first detector that is configured to receive photons excited by the first high energy photon emitter from the first location on the core or rock sample along a first detection axis. A first collimator surrounds the first detection axis. The first collimator is removably coupled to the assembly.
