The invention provides a device for measuring screw element at pipe end, a system for measuring screw element and a method for measuring screw element. A first screw element is measured by detecting light which is substantially parallel with a screw groove (A4) among lights leaked to the side opposite to a light source (21) with respect to the axis of pipe with use of an optical sensor (2). A second screw element is measured by touching the contact probe (31) of a contact sensor (3) to the flank face (A8) of a screw and detecting the spatial coordinate of the contact probe (31) at the time ofcontact. The first and second screw elements thus detected are synthesized by an operation processing means (4) and a screw element of a measurement object screw is operated.

The invention provides a multi-line scanning laser radar device, which comprises a moving part and a fixed part which are connected by a rotary support, wherein a laser emitting optical system and a laser receiving optical system are arranged inside the moving part in parallel; a driving motor is arranged inside the fixed part and is fixedly connected with the rotary support through a rotating shaft; and the laser emitting optical system, the laser receiving optical system and the driving motor are electrically connected with a driving control system respectively. The aim of performing multi-line three-dimensional scanning on an imaging target is fulfilled, and the imaging speed and the imaging quality are improved.

The scattering vector of X-ray diffraction is dynamically displayed on a screen. A dynamic motion and tracks of the tip location of the scattering vector of X-ray diffraction is displayed two-dimensionally or three-dimensionally under changing measuring conditions on a screen which represents the reciprocal space of a sample crystal. The tip location of the scattering vector can be seen dynamically and the X-ray diffraction phenomenon under changing measuring conditions can be readily understood, effecting easy consideration of the measuring conditions and easy evaluation of the measured results.

The invention relates to a track-measuring vehicle (1) for recording a track geometry of a track (2), having a vehicle frame (5) which can move on two rails (3) of a track and has rail bogies (4), andhaving a first measuring base (7) on which an inertial measuring unit (8), and at least one contactless position-measuring device (9) for determining the position with respect to each rail (3), are arranged. There is provision here that a lowerable second measuring base (11) is arranged, which second measuring base (11) comprises measuring running wheels (12), which can be set down on the rails (3), and is connected to the first measuring base (7) via compensation-measuring devices (20, 22).
