Latest Patents

Johansen's latest innovations include cutting-edge gas sensors designed to measure the concentration of predetermined gases. One of his notable patents describes a gas sensor that incorporates a light source to emit pulses of light. This sensor features a measurement volume, a detector for capturing light that has passed through the measurement volume, and an adaptable filter. The gas sensor operates in distinct states, passing specific wavelength bands absorbed by the gas in its measurement state while attenuating these wavelengths in a reference state. A controller orchestrates the operation of the light source, detector, and adaptable filter, allowing for dynamic adjustments during sensor operation.

Another significant patent involves a sophisticated field detector comprising a field-responsive element that undergoes dimensional changes when exposed to specific fields. This patent outlines an interferometric read-out arrangement that captures the dimensional shift of the field-responsive element. The setup includes a light source providing both a measurement beam and a reference beam, with an optical detector capturing the interference pattern formed by these beams. The field-responsive element features a curved surface constrained at an edge, ensuring that dimensional changes alter the optical path length of the measurement beam, thus modifying the detected interference pattern.
