Study on the angular displacement compensation of filter function in the 4f optical system

To measure dynamic stabilization precision of airborn electro-optical system,a measurement scheme of angular displacement of real-time variable frequency is put forward.

The characteristic of angular displacement was one of the main characteristics of the torque motor.

Principle and Use of Kind of Angle-displacement Eddy-current Transducer;

By analyzing the principle of capacitance sensor measuring the angle-displacement,this paper first provides a design idea that changes output voltage to pulse signal,and every pulse stands for a certain amount angle-displacement.

According to the conclusion,the irrotational displacement isolator which can converse angular vibration to linear vibration is designed.

Based on the requirements of irrotational displacement vibration reduction for airborne opto-electronic platform,a new parallel motion mechanism as a vibration reduction mechanism is brought up.

We consider that the discrete loci of a line are composed of a series of horizontal displacements or diagonal displacements,which can be easily determined from an iteration formula.

The algorithm is presented on the observation that the discrete loci of a circle are composed of a series of horizontal displacements and diagonal displacements.
