| Summary:
The curved spacetime induced by gravitational waves can give rise to visual
effects such as geometric distortions and redshift structures in the observed
image. By establishing a mapping from the object’s surface coordinates to the
observer’s screen coordinates, we study these effects in the context of plane
gravitational waves. The simulation reveals that the image of an object doesn’t
merely seem compressed or stretched, but rather appears twisted and wobbled.
Furthermore, the redshift structure on the object’s surface appears to rotate
as a whole. This outcome offers an intuitive depiction of the lensing effect in
plane gravitational wave spacetimes.
