  • Cutting-edge mobile phones and tablets marketed by Apple, equipped with a LiDAR sensor, are able to measure the three-dimensional position of objects and reconstruct their surface. At present, specific publications illustrating the potential of this sensor in the field of archaeology are not known. The first part of the article explains its functioning; the second deals with its limitations; the third describes its use in an architectural survey of two buildings;

    the fourth proves its usefulness in the architectural field, particularly in the study of archaeological standing buildings (archaeology of architecture). In light of the tests performed, it can be stated that the LiDAR offers centimetre-level accuracy and is therefore of great interest in the field of archaeology, also considering its relatively low cost, its ease of manoeuvring and fast acquisition of data, compared to other scanning systems. The LiDAR may become a common tool in the field of archaeology in the future if investments in this technology continue, producing sensors capable of measuring more accurately (the current maximum coverage is 5 m) and software (apps) that can produce flawless textures and more uniform sampling of space. In its current state of development, the sensor is not suitable for precise modelling of small-size objects, while it is useful for the archaeological documentation of masonry, architectural elements and walls. In addition, it is the ideal tool for obtaining floor maps and three-dimensional models of small-sized environments.
