Latest Patents
Among John W. Hardy's notable inventions is the Variable Shear A.C. Interferometer, which serves as a wavefront sensor utilizing a surface acoustic wave diffraction grating. This advanced wavefront sensor detects the slope of an input wavefront by employing a reflective diffraction grating positioned at the wavefront's focal point. The device generates surface acoustic waves at two primary frequencies, f1 and f2, facilitating the production of a first AC shearing interferogram. A photodetector array captures the interferogram across a two-dimensional array of zones, allowing for the determination of the local slope of the wavefront in the shearing direction. Additional two-dimensional wavefront slope information is obtained by utilizing a second surface acoustic wave diffraction grating and photodetector array, offering comprehensive insights into wavefront behavior.
