Rapid-response high-precision electronic accelerator

The invention provides a rapid-response high-precision electronic accelerator and relates to the technical field of electronic accelerators. The rapid-response high-precision electronic accelerator comprises a grating type displacement sensor, a shaft rod, an adjustable stop block and a cardan joint connecting shaft. The grating type displacement sensor comprises a shell. A protruding installation cavity is arranged in the middle of the shell. An inner light source, a first optical lens, a second optical lens and a photoelectric element are sequentially arranged in the installation cavity and located on the same center line. The right end of the shell is provided with an end cap. An indication grating and a scale grating are arranged between the first optical lens and the second optical lens. A sliding groove is formed in the surface of the side, close to the scale grating, of the indication grating. A sliding strip is arranged on the surface of the side, close to the indication grating, of the scale grating.
