Latest Patents

Hakan Bergstrom holds a patent for a device and method for measuring birefringence in an optical data carrier. This device incorporates a laser light source with a polarization modifier, a beamsplitter, a polarizer, a photodetector, and a controller connected to the photodetector. The laser light source illuminates various spots on the optical data carrier using a laser beam. The photodetector captures the reflected laser beam, converts it into an electric signal, and sends this signal to the controller. The controller then determines the birefringence value in the illuminated spot on the optical data carrier. Additionally, the device includes a transparent reference element with known birefringence properties, a mirror, and mechanisms for directing the laser beam during calibration and measurement phases.
