A method and device for determining values of a magnetic field component of a magnetic vector field.

A method for determining values of a magnetic field component of a magnetic vector field, comprising: determining first distribution data comprising values of the magnetic field component, for a first predetermined area defined along a predetermined surface; determining second distribution data comprising second values of the component of the magnetic field for a second predetermined area defined along a second predetermined surface, wherein the first and the second predetermined surfaces are parallel;
wherein determining second distribution data comprises manipulation of the first distribution data based on making use of intrinsic physical properties of the magnetic field; and associated device.

The present device relates to a sensor capable of detecting changes in the electromagnetic field it generates when in proximity to either conductive or nonconductive materials. This occurs by way of oscillating a transmit coil with an electro motive force at a resonant frequency thus creating an electromagnetic field. The magnetic field passes through a target of either conductive or nonconductive material and is then intercepted by a receive coil which likewise oscillates at a resonant frequency, which when in proximity to the transmit coil and transmit coils resonant frequency produces an enhanced signal by way of the interaction of the respective resonant frequencies and receive coil output.

A near eye display metrology device that is compact and will work with longer focal lengths such as those needed for windshield heads-up-display (HUD) and augmented reality heads-up-display (AR-HUD). The device includes an XY galvanometer having a pair of mirrors to controllably deflect an expanded beam traveling along the optical axis in an X dimension and in the Y dimension. An auto-focus assembly is positioned along the optical axis and a controller is coupled to the motors and programmed to correct for any distortions in the device and to control the auto-focus assembly. At least one aperture is positioned along the optical axis and oriented to reduce the measurement field angle of the device and to block any out-of-focus illumination. A spectrograph including a component configured to disperse light onto an imager is used to obtain test results.
