The control unit is configured to control a display unit in such a manner that an irradiation position of the measurement light is displayed on the image captured by the image capturing unit.

According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: controlling one or more electroacoustic transducers of a device to create a standing wave having a displacement antinode at an expected location of a component of the device; receiving a signal representing sound generated by vibration of the component driven by the standing wave; causing analysis of the signal to determine whether there is a defect based on whether the signal represents a sound that would be expected to result from vibration of the component driven by the standing wave in the absence of a defect.

According to one embodiment, a control method includes setting a transmission angle of an ultrasonic wave to a standard angle. The control method further includes transmitting an ultrasonic wave at the set transmission angle and detecting an intensity of a reflected wave from an object. The control method further includes calculating a tilt angle based on a gradient of the intensity. The tilt angle indicates a tilt of the object. The control method further includes resetting the transmission angle based on the tilt angle.

A device and method used to image wells and other fluid-carrying tubulars having localized features of interest. The device scans large areas of the tubular first in a low-resolution mode, then identifies areas that contain those localized features with some probability. The device images the identified areas in a high-resolution mode and stores the images for further image processing. The device may comprise two sensors axially spaced-apart on the device, which sensors may be electromagnetic, acoustic, or cameras.

A device and method used to image wells and other fluid-carrying tubulars having localized features of interest. The device scans large areas of the tubular first in a low-resolution mode using an ultrasound sensor and in a high-resolution mode using a camera, then identifies areas that contain those localized features with some probability.
