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.

The invention discloses an imaging system. The imaging system may include an image sensor with phase detection pixel groups for depth sensing or automatic focusing operations. Each phase detection pixel group may have two or more photosensitive regions covered by a single microlens so that each photosensitive region has an asymmetric angular response. The imaging system may use image data from thephase detection pixel group to determine a phase difference. Alternatively, to improve accuracy, the imaging system may obtain two sets of image data using two different aperture sizes. The phase difference associated with each aperture size may be determined. The difference between the two phase differences may be determined and used as a more accurate metric for depth sensing or automatic focusing operations.

A solar sensor that utilizes a blocking element and curved reflective element between the sun and a photo-sensitive electronic device to provide high signal levels and the ability to shape the angular response of the overall sensor. A particular angular response can be achieved by combining the attenuating affects of the blocking element with the increased response affects of the curved reflector. These two elements may be combined into one physical structure, or may be separate. Further, the present invention contemplates the use of multiple blocking elements and multiple reflectors.

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.

The invention provides a speed vector directive driving method for unmanned aerial vehicle human-in-the-loop head-up display. According to the method, under the condition that no effective attack angle signal is measured, according to the correlation derivation of angle-of-attack change and normal overload increment, a pseudo angle of attack is constructed on a ground console by using effective normal overload information downloaded by an unmanned aerial vehicle to simulate a real angle of attack, so that the pseudo angle of attack is used for driving the display of a head-up display speed vector directive of a flight control comprehensive picture display area of the ground console. According to the method, the response polarity of the pseudo angle of attack is correct and basically free of delay in the maneuvering process of the unmanned aerial vehicle, the response amplitude basically coincides with that of a normal angle of attack in the operation of medium and small rods, and the response amplitude is slightly smaller than that of a normal angle of attack in the operation of a large rod, so that the use requirements are met.
