Lens Aberration & Fourier Optics Kit
Description
In an ideal optical system, all rays of light from a point in the object plane would converge to the same point in the image plane, forming a clear image. A perfect lens would show the image of a point as a point and a straight line as a straight line, but in practice, lenses are never perfect. 6 experiments in this kit illustrate why we can’t see a “true image”.
The Fourier transform properties of a lens provide numerous applications in optical signal processing. Spatial filtering is one of the most important one, which will be explained in the 7th experiment.
Experiments
1. Spherical Aberration
2. Curvature of field
3. Astigmatism
4. Coma
5. Distortion
6. Chromatic aberration
7. Chromatic aberration
