Tripod head for precision apparatus e.g. infrared camera, has control unit to control magnetic field generating elements so that mechanical damping of mounting pin and locking of mounting pin are adjusted

摘要

The tripod head (1) has a contact region (12) that is filled with electrical/magneto rheological fluid (6). A ball head portion (3) is pivotally mounted in a mounting portion (4) of a ball-and-socket joint (2). The viscosity of rheological fluid is varied at the contact region through electrical and/or magnetic field (13) generated by generating elements (18,19). A control unit is provided to control the electrical and/or magnetic field generating elements so that mechanical damping of mounting pin (11) and locking of mounting pin are adjusted.
