MINIATURIZED ADAPTIVE OPTICS WITH DEFORMABLE PHASE PLATE FOR DIGITAL TILT AND ABERRATION CORRECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18370367 titled 'MINIATURIZED ADAPTIVE OPTICS WITH DEFORMABLE PHASE PLATE FOR DIGITAL TILT AND ABERRATION CORRECTION

Simplified Explanation

The camera system described in the patent application includes an optical assembly, a deformable phase plate (DPP), an image sensor, an image signal processor, and an estimator. The DPP has a deformable surface suspended over a cavity filled with optical fluid, with electrical actuation elements that change the shape of the surface based on a control signal. The image sensor converts the adjusted optical image into electrical signals, which are then processed by the image signal processor to generate a digital image. The estimator estimates aberration or tilt correction of the digital image and generates the control signal based on this estimation.

Unanswered Questions

How does the control signal affect the shape of the deformable surface in the DPP?

The control signal triggers the electrical actuation elements to change the shape of the deformable surface, but the specific mechanism of this interaction is not detailed in the abstract.

What is the accuracy and speed of the aberration or tilt correction process in this camera system?

While the estimator is mentioned to estimate aberration or tilt correction, the abstract does not provide information on the accuracy or speed of this correction process.


Original Abstract Submitted

In some embodiments, the camera system comprises: an optical assembly to create an optical image from the optical wavefront; a deformable phase plate (DPP) to receive the optical image from the optical assembly and to adjust the optical image in accordance with a control signal, the DPP including a deformable surface suspended over a cavity filled with optical fluid, and electrical actuation elements configured to change a shape of the deformable surface based on the control signal, the electrical actuation elements arranged in a pattern in the cavity and, when activated, provide an electrostatic force on the deformable surface; an image sensor to convert the adjusted optical image into electrical signals; an image signal processor to generate a digital image from the electrical signals; and an estimator to estimate an aberration or tilt correction of the digital image and to generate the control signal based on the estimated aberration or tilt correction.
