Systems and methods for improving x-ray sources with switchable electron emitters. Improved systems may use the functionality of the switchable electron emitters in various configurations to provide power regulation, multidimensional analysis, and electron beam forming so as to increase the durability and the reliability of the system. Cooling mechanisms may be used to further protect the anode from deterioration over time.

Systems and methods for improving x-ray sources with switchable electron emitters

A system evaluates a point of gaze of a user on an object and includes at least one eye tracker camera and at least one positioning camera. The eye tracker camera and the positioning camera are configured to be arranged in fixed positions relative to each other. At least one light source is configured to provide conical reflection from at least one of a user's eyes. At least one computer and at least one object is provided. The geometrical data of the object is stored in a storage device accessible to the computer. Wherein the computer is configured to determine: a gaze line of said user relative to a 3D coordinate system, the position of said at least one object relative to said 3D coordinate system, and a gaze point calculated as the intersection of said gaze line with the surface of said object in said 3D coordinate system.

A method for calibrating an eye tracker includes drawing the attention of a user to a calibration target. At least one positioning camera and at least one computer is employed to determine the position of the calibration target and the eye tracker coordinate system relative to each other. The calibration parameters of a gaze line are determined, to the calibration target, in a first coordinate system. The above steps are repeated, thereby providing a desired part of a gaze range and calibration targets distribution. The calibration data is then stored. A method of calibrating and using an eye tracker and a method of calibrating an eye tracker for use with a display are also provided.
