The vacuum chamber is prepared using glass material, and the upper substrate, main substrate and subtegulum are all made of siliceous material Material is prepared.

Compared with the prior art, the advantages of the present invention are as follows:

The sub- gyro of a kind of microcomputer electric light suspension rotating particle of the invention is one kind based on MEMS technology technology, in main substrate On obtained and will test laser source systems, optical waveguide systems, vacuum chamber and the detection device portions such as Electro-Optic Sensor System To novel theoretical calculation precision be up to 10-11°/the high-precision small size gyro of h.The core devices of the gyro are in laser Lower particulate of the stable suspersion in vacuum chamber is acted on, according to the momentum interaction principle of laser, particulate is in microcobjective The light intensity of formation after convergence in equal light field, is not suspended in steadily in vacuum chamber under the action of optical gradient forces, leads at this time Laser becomes circularly polarized laser after crossing quarter wave plate effect, and circularly polarized laser acts on particulate, the rotational momentum hair of laser Changing, so that active force is generated to particulate, so that particulate realizes rotation under the action of circularly polarized laser, due to vacuum Middle smooth aerosols damping is very small, and the particulate of rotation can achieve high revolving speed, reaches as high as 1GHz, generally may be used In 1MHz or more, much higher than the revolving speed (several hundred Hz) of conventional mechanical rotor.It is good fixed to be had according to the object of ultrahigh speed rotation Axis still can keep the rotation axis of itself constant after carrier rotation, and then high-speed rotating particulate just realizes Excellent gyroscopic inertia, his rotation axis do not change.At this time by detecting the spatial attitude of particulate rotation axis Angle can obtain the angle and angular velocity information of motion carrier further according to the gyroscopic inertia of ultrahigh speed rotating particle.

The present invention is suspended in the particulate in vacuum chamber due in no laser action and vacuum chamber bottom interior wall is direct Contact, on microscopic fields, since the scale size of particulate is several hundred nanometers to tens microns, intermolecular Van der Waals at this time Power will become a very important factor, and in the initial time of laser action, Van der Waals force suffered by particulate will be significantly big Trapping stiffness under laser action can reliably suspend to guarantee particulate in an initial condition, so initial to particulate Apply an effect of vibration, the constraint of Van der Waals force can be got rid of, therefore piezoelectric ceramics substrate is installed into vacuum chamber bottom (PZT), the vibration at high speed that vacuum chamber is driven by the vibration at high speed to piezoelectric ceramics substrate, so that the particle in vacuum chamber Son gets rid of the constraint of Van der Waals force in the initial state, is reliably achieved suspension.

Upper substrate lower part of the invention is equipped with the detection photoelectric sensor that suspends, and believes for the sub- position of detection of particles and with frequency Breath, the detection photoelectric sensor that suspends is by receiving from the laser beam by particulate, by dividing laser amplitude phase Analysis compares to obtain the position obtained particulate in the vacuum chamber and frequency information.

In the present invention, when particulate stable suspersion will become circular polarization in vacuum chamber and then addition quarter wave plate, laser State laser.Particulate under the action of the circular polarization state laser in gyro just starts high speed rotation, is swashed using a branch of circular polarization Light light beam forms rotary optical potential well after ligh trap Force system, and particulate is driven to make high speed rotation, to realize in gyro The photic rotation of particulate achievees the purpose that the manipulation of particle angular speed and control in gyro.

Subtegulum of the invention is equipped with suspension laser source, microcobjective and quarter wave plate, and collection suspends and rotation function is one Body can reliably guarantee that the particulate in vacuum realizes high speed even ultrahigh speed rotation after stablizing rotation, for lower base Spacing distance between piece and main substrate needs specific control according to actual needs to realize optimal performance.

When carrier rotates, due to gyroscopic inertia, its rotation axis can be kept not the particulate that ultrahigh speed rotates in carrier Become, the space attitude angle so as to cause rotation axis and carrier can change.Therefore pass through real-time measurement particulate Spatial attitude, and the size for parsing extraneous input angular velocity counter can be pushed away by the variation at the spatial attitude angle of particulate. The spatial attitude of real-time measurement particulate is the key that present invention high-precision, small size gyro.In order to realize particle subspace appearance State angle, angular velocity of rotation size and Orientation measurement, the present invention be respectively equipped on main substrate detection laser source systems and with The corresponding detection Electro-Optic Sensor System of difference.The weak detection laser irradiation launched by detection laser beam is to suspension The particulate that ultrahigh speed rotation is done under state, under the action of rotating particle, phase can occur for the amplitude and frequency of weak detection laser The variation answered is swashed by the weak detection for receiving irradiated particulate in the corresponding detection Electro-Optic Sensor System of main substrate at this time Light is analyzed by amplitude, the frequency to the weak detection laser received, by the amplitude and frequency with initial weak detection laser Rate compares the spatial attitude angle that can obtain particle, and the variation after the spatial attitude angle of particulate counter can push away solution The size of extraneous input angular velocity is precipitated.

In the present invention, in order to guarantee that particulate can be steadily suspended in vacuum chamber by laser, reliable vacuum is needed Environment guarantees that reliable vacuum degree is equipped with getter in vacuum chamber.It is placed on the subtegulum of the lower section of main substrate and integrates at this time Suspension laser source, suspension laser source are placed in the lower section of the vacuum chamber of main substrate, by the work of switch control suspension laser source, It acts on forming the light field that intensity does not wait using high order focusing possessed by the laser through microcobjective, under the action of trapping stiffness By the molecule stable suspersion at the maximum position of light intensity, the particulate in vacuum chamber can be steadily suspended at this time In transparent vacuum chamber.
