An apparatus for monitoring mechanical integrity of an eye-safety component of an illuminator is disclosed. The apparatus comprises a transducer operable to create a vibration in the eye-safety component, a sensor operable to sense the vibration in the eye safety component and to output a signal representative of the sensed vibration, and a processor. The processor is operable to: monitor the signal from the sensor; determine if the signal comprises at least one parameter that falls outside of a pre-determined acceptable range, the pre-determined acceptable range being indicative of mechanical integrity of the eye-safety component; and initiate a safety action in response to a determination that the at least one parameter falls outside of the pre-determined acceptable range thereby indicating a loss of mechanical integrity.

The three-dimensional standard vibrator based on the aerostatic gas-floating decoupling device contains a base. The base is installed with a X axis vibrator, a X axis return mechanism, a Y axis vibrator, a Y axis return mechanism, a Z axis vibrator, and a three-dimensional vibration platform. The X axis vibrator and the X axis return mechanism are both installed along X axis but separated by the three-dimensional vibration platform. The Y axis vibrator and the Y axis return mechanism are both installed along Y axis but also separated by the three-dimensional vibration platform. There are two aerostatic gas-floating plates corresponding to the vibrator and connecting to the X axis and Y axis vibrators, respectively. Two intervals used to generate gas films are formed between the two aerostatic gas-floating plates and the three-dimensional vibrator, respectively. The X axis and Y axis return mechanisms both consist of a reset spring and an aerostatic gas-floating plate corresponding to the spring. The Z axis vibrator is connected with the Z axis aerostatic gas-floating decoupling device. There are intervals used to form gas films between the Z axis aerostatic gas-floating decoupling device and the three-dimensional vibration platform. The present invention contains the advantages of high loading capacity, supporting stability and uniformity.
