A portable survey instrument and methodology yield intensity of neutron radiation, intensity of gamma radiation, and a direction of impinging gamma radiation. The instrument uses a neutron detector surrounded by an essentially rectangular moderator with preferably four gamma ray detectors disposed symmetrically about the neutron detector and within the moderator. Material and dimensions of the moderator are selected so that the neutron-measurement is equally sensitive to fast and thermal neutrons. The moderator also induces angular responses to the gamma ray detectors. Responses of the gamma ray detectors are combined to yield a parameter indicative of the angular position of a source. The survey instrument is portable and suited for hand held use.

Field probe from the angular response of a rigid body
Probing incident radar fields in a target test zone of a RCS test facility by exploiting angular radar response of a long and uniform rigid body supported horizontally across or vertically through the test zone. The rigid body is free to rotate about the broadside condition. Thus, the angle of the rigid body is gradually changed with respect to the direction of arrival of the incident wave. Radar echo from the rigid body is measured as a function of the rigid body angle. The data is then processed to yield a profile of the incident wave intensity along the rigid body. By varying the azimuth angle continuously while recording radar data, the data may be processed by the fast Fourier transform (FFT) algorithm to yield a profile of the incident wave intensity along the rigid body.

A neutron monitor adopted by the invention helps to solve the problems about on-site monitoring and magnitude transmission of high-energy and wide-spectrum neutron radiation fields. The neutron monitor probe is designed in a directional and moderated manner. Fissionable metal materials are embedded into the moderators, so a (n, f) fission reaction is utilized to widen the measuring range of high energy neutrons. Neutron reflective materials are embedded into the moderators, so angular response and energy response can be improved. The directional wide-energy-range neutron monitor probe has the characteristics of novel structure, wide monitored neutron energy range, good angular response feature and the like.

Image sensors with calibrated phase detection pixels, and operation method thereof
The invention relates to image sensors with calibrated phase detection pixels, and an operation method thereof. Image sensors may include phase detection pixels that are used to determine the distancebetween the image sensor and objects in a scene. To account for variations in the angular response of phase detection pixels across a pixel array, calibration may be performed. During calibration, animage sensor may take images of targets at known distances from the sensor. The known distances may be used to determine scaling factors that account for differences between the initially calculateddistances between the sensor and the targets and the actual distances between the sensor and the targets. The scaling factors may then be stored on the image sensor for future reference. During subsequent use of the image sensor, the image sensor may then obtain the appropriate scaling factor in real time for more accurate phase and distance determinations.
