Devices, methods, and computer program products for measuring the speed of an object. A speed measuring device includes a rangefinder module configured to measure distances from the device to a target object. Activating the device causes the device to measure a first distance from the device to the object along a first line-of-sight, and a second distance from the device to the object along a second line-of-sight. The device determines an angular displacement between the first line-of-sight and the second line-of-sight, and one or more of an elapsed time between measuring the first distance and measuring the second distance and a radial velocity of the object. The device then determines the absolute speed of the object based on the first distance, the second distance, the angular displacement, and one or more of the elapsed time and radial velocity.

A measuring head (1; 1a) for a tactile coordinate measuring device (22), in particular an exclusively tactile coordinate measuring device, which has several sensor devices (3, 5; 3a, 5a) for determining at least one measured value at least at one measuring point (15). Advantageously, a first sensor device (3; 3a) comprises a tactile sensor and a second sensor device (5; 5a) comprises an optical detecting means (19), wherein both sensor devices (3, 5; 3a, 5a) can be connected to the tactile coordinate measuring device (22) by a single connecting section (9; 9a). Advantageously, an existing tactile coordinate measuring device can be converted into a multi-sensor coordinate measuring device without structural modifications. Furthermore, the invention relates to a method for measuring a workpiece with a tactile coordinate measuring device and a coordinate measuring device.

An imaging system includes an imaging device configured to image an imaging subject on an imaging optical axis, and a calculation unit configured to acquire data relating to a position and/or a size of the imaging subject based on image information acquired by the imaging device through the imaging. The calculation unit acquires change information relating to condition change in the imaging and/or change in the imaging subject on the image. The change is caused by interposition of a light transmitting member when the light transmitting member is interposed on the imaging optical axis during the imaging, and the calculation unit corrects the data based on the change information.
