CS international – with two presentations from the Hub affiliates:
The High end sensor is a workshop with CS international, 10/11th April, Brussels
Quantum Well Hall Effect (QWHE) sensors for Non- Destructive Imaging applications.
Mohamed Missous – University of Manchester
A new class of highly sensitive Quantum Well Hall Effect (QWHE) sensors have been developed and commercialised. These magnetic sensors include single, linear and 2D arrays magneto-vision systems. DC and AC magnetic fields can be measured with magnetic and spatial resolutions of < 50nT and 0.5mm respectively. Using specially integrated AC illumination coils, these magnetic cameras can be used to detected defects and flaws in magnetic and nonmagnetic materials. Using advanced DSP and high-resolution ADCs, the systems can increase AC and DC magnetic field scanning frame rate and reconstruct images by measuring AC magnetic field at different frequencies.
