  • Crosstalk reduction in piezo printhead
    Patent number: 8757750
    Abstract: Crosstalk in a piezo printhead is reduced by selecting an actuation signal for a nozzle, determining a time delay and a pulse width extension based on adjacent actuation signals of adjacent nozzles, and applying the time delay and pulse width extension to the actuation signal.
    Type: Grant

  • Light steering using an array of tunable phase delay elements
    Patent number: 7626754
    Abstract: An apparatus and method for steering a beam of light using an array of tunable optical phase delay elements is presented. The sidelobes of an angular spectrum of light reflected from the array are causing an optical crosstalk. The selected sidelobes are suppressed by perturbing the phase delay pattern of the array elements. The pattern of perturbations is found by linearizing a system of equations describing dependence of the angular spectrum of the reflected light on the phase delays introduced into the wavefront of light by the elements of the array.
