摘要：An optical component mount with beam deviation monitoring and beam guiding system using such optical component mounts. The optical component mount has a location for mounting an optical element thereon for operating on the beam and at least one sensor attached to the optical mount at a predetermined position. The predetermined position is selected depending on the state of the optical component mount. The state can be, e.g., a vibrational state or a thermal expansion state. The predetermined position is chosen near or at an anti-node of at least one mode contributing to the state but not at a node of any mode expected to contribute to the state of the optical mount. The state of the optical mount is determined based on the signals obtained from the at least one sensor, which can be an accelerometer in the case of monitoring a vibrational state or a temperature sensor in the case of monitoring a thermal expansion state. The sensor is preferably embedded in the optical mount and the deviation of the beam is then determined from the state of the optical mount. Optical mounts according to the invention can be used in any beam guiding system including but not limited to those found in optical and/or opto-electronic assemblies.
