Abstract
A wavefront control apparatus includes a detector configured to detect a signal generated from a medium onto which light is irradiated, and a controller configured to control a wavefront of the light based on an output of the detector. The controller performs first processing for forming a first wavefront of the light based on the signal generated from a first measurement position in the medium, and second processing for forming a second wavefront of the light based on the signal generated from a second measurement position different from the first measurement position in the medium onto which the light having the first wavefront is irradiated.
Claims17
A wavefront control apparatus comprising:
- a detector configured to detect a signal generated from a medium onto which light is irradiated;
- and
- a controller configured to control a wavefront of the light based on an output of the detector,
- wherein the controller performs:
- processing for forming a first wavefront of the light based on the signal generated from a first measurement position in the medium,
- processing for setting a second measurement position in the medium different from the first measurement position in the medium based on the signal generated from the medium onto which the light having the first wavefront is irradiated, and
- processing for forming a second wavefront of the light based on the signal generated from the second measurement position in the medium onto which the light having the first wavefront is irradiated.
A wavefront control method configured to control a wavefront of light to be irradiated onto a medium, comprising:
- forming a first wavefront of light based on a signal generated from a first measurement position in the medium;
- setting a second measurement position in the medium different from the first measurement position in the medium based on the signal generated from the medium onto which the light having the first wavefront is irradiated;
- and
- forming a second wavefront of the light based on a signal generated from the second measurement position in the medium onto which the light having the first wavefront is irradiated.
A non-transitory computer-readable storage medium storing a program that enables a computer to implement a wavefront control method configured to control a wavefront of light to be irradiated onto a medium,
- wherein the wavefront control method comprises:
- forming a first wavefront of light based on a signal generated from a first measurement position in the medium;
- setting a second measurement position in the medium different from the first measurement position in the medium based on the signal generated from the medium onto which the light having the first wavefront is irradiated;
- and
- forming a second wavefront of the light based on a signal generated from the second measurement position in the medium onto which the light having the first wavefront is irradiated.
