摘要:
The invention relates to a method of producing a movable lens structure that comprises the steps of: forming a lens from a lens material disposed on a carrier of another material (step 58), and forming a micromechanical structure from the carrier (step 60), wherein the forming of the lens takes place before the forming of the micromechanical structure. With this method a simplified production method is obtained that simplifies difficult compatibility requirements between micromechanics and lens that can otherwise be hard to meet.
摘要:
An opto-electronic A/D converter includes a tunable laser for wavelength modulating a narrowband coherent electromagnetic beam by the amplitude of the analog signal. A grating transforms the wavelength modulated beam into a corresponding angularly modulated beam. A set of kinoforms diffract the angularly modulated beam into a bundle of diffracted beams. Detectors determine the digital signal by repeatedly sampling the spatial power distribution of the diffracted beams.
