  • Publication number: 20250362236
    Abstract: A inspection apparatus includes a light-emitting part that emits light, a first align key attached to one side of the light-emitting part, a light-receiving part disposed to be spaced apart from the light-emitting part in a first direction and receiving the light emitted from the light-emitting part, and a camera attached to one side of the light-receiving part, disposed to be spaced apart from the align key in the first direction, and capturing the first align key.

  • Patent number: 11303270
    Abstract: A method and an ultrasound system are provided for generating transmission signals of an ultrasound probe used in a contrast-enhanced ultrasound image mode. The ultrasound system generates a pair of pulse control signals n and n+1 and a damping compensation pulse control signal, generates a pair of pulses n and n+1 having polarities opposite to each other and a damping compensation pulse having a polarity opposite to that of the n+1-th pulse based on the pair of pulse control signals and the damping compensation pulse control signal, transmits transmission signals including the pair of pulses and the damping compensation pulse, generates an ultrasound signal based on the transmission signals, transmits the ultrasound signal to a target object, and acquires echo signals for forming a contrast-enhanced ultrasound image of the target object. The damping compensation pulse is successively generated after generating the pair of pulses.

  • Publication number: 20160131593
    Abstract: A surface inspection apparatus and method, and a method of manufacturing a display device are disclosed. In one aspect, the surface inspection method includes placing an object on a stage comprising a top surface inclined at a predetermined angle with respect to a plane having a first direction and a second direction crossing the first direction. The method also includes irradiating light onto the object via a surface inspection unit. The method also includes obtaining a first image comprising first interference fringes captured by the imaging device, moving at least one of the surface inspection unit and the stage in at least one of the first and second directions, obtaining a second image including second interference fringes captured by the imaging device, and moving the surface inspection unit in the third direction so as to correct movement of the second interference fringes with respect to the first interference fringes.
