Hello everyone,
I’ve been racking my brain to try to figure out the image aberration balance method with unknown lens design data method, the optical sketch is shown below,the camera is put at the final image plane, the current final image is not so good. the problem is the there is an unknown design in this optics train, so I can neither adjust nor redesign the following components to balance the final image aberration. I come up with a method which is: i put an image aberration sensor at the first image plane, the sensor would read out the first image aberration in terms of Zernike coefficients, then I start a new design, i put a dummy surface which contains the first image aberration in terms of Zernike coefficients at the first image plane position. and then I can adjust or redesign the following components in this optical train. Do this method make sense?
What is the unknown design? Is the imaged object inside it, or in front of it? If the object is in front of it, you might try projecting an image backward from the camera position or from the known system through the unknown system.
