    Contact type automated inspection systems are:

    1) Inspection probe
    2) Flexible inspection system
    3) CMM

    - Inspection probe is a contact type of automated inspection method. This method uses touch-sensitive mechanical or optical sensor to make contact with the component. If inspection probe comes in contact with the test specimen, signals are transmitted by the sensor to processing unit.

    Non-contact type automated inspection systems are:

    1) Machine vision
    2) Laser scanning
    3) Ultrasonic technique
    4) Electric field
    5) Radiation technique

    - Laser scanning systems use low energy lasers to measure linear dimensions.

    - Electric fields are created by an electrically active probe.
