ABERRATION CORRECTION OF A SPATIAL LIGHT
The construction of liquid crystal spatial light modulators is imperfect, leading to aberrations in its surface. These aberrations decrease the quality of the light fields that can be formed with the device.
High-Precision Calibration of Phase-Only Spatial Light Modulators
We are creating commercial displays using dynamic phase-only spatial light modulators (SLMs). The main advantages of this approach are light efficiency and fault tolerance.
Wavefont Correction Technique of Spatial Coherent Optical
After calibration, the phase–grayscale relationship diagrams of the LC-SLM under various wavelengths are presented, and the feasibility of using the LC-SLM to correct the wavefront distortion
Phase response calibration method for liquid crystal spatial light
By employing experimental calibration curves for nonlinear correction, the nonlinear error of the phase-gray modulation characteristic curve was reduced from 8.39% to 2.68%, validating the

We present a liquid crystal method of correcting the phase of an aberrated wavefront using a spatial light modulator. A simple and efficient lab model has been demonstrated for wavefront correction.
Correction for the inherent aberration of liquid crystal spatial light
After the aberrations being measured with a wavefront sensor, the correction wavefront is automatically obtained by analyzing these aberrations. Then, the correction wavefront can be used to

Spatial Light Modulator Principles
Correction is accomplished by using two spatial light modulators in series. The first performs the necessary amplitude modulation, also introducing a phase change. The second SLM restores the
