Abstract
A wavefront sensor includes a line-focusing element, a line sensor, and a wavefront aberration estimator. The line-focusing element focuses, in a line, light travelled through a medium. The line sensor receives the light focused in a line to obtain a one-dimensional image of the light. A wavefront aberration parameter estimation unit included in the wavefront aberration estimator inputs a pre-processed image of the one-dimensional image to a wavefront aberration parameter estimation model trained by machine learning and causes the wavefront aberration parameter estimation model to output a wavefront aberration parameter representing a wavefront aberration due to the medium.
Claims7
A wavefront sensor, comprising:
- a line-focusing element that focuses, in a line, light travelled through a medium;
- a line sensor;
- and
- a wavefront aberration estimator, wherein
- the line sensor receives the light focused in a line by the line-focusing element to obtain a one-dimensional image of the light,
- the wavefront aberration estimator includes an image pre-processing unit and a wavefront aberration parameter estimation unit,
- the image pre-processing unit pre-processes the one-dimensional image to generate a pre-processed image, and
- the wavefront aberration parameter estimation unit inputs the pre-processed image to a wavefront aberration parameter estimation model trained by machine learning and causes the wavefront aberration parameter estimation model to output a wavefront aberration parameter representing a wavefront aberration due to the medium.
