All 'delayed choice quantum eraser' experiments are explained by understanding conservation of momentum and a moving particle has an associated aether displacement wave.

When the downconverted photon pair are created, in order for there to be conservation of momentum, the original photons momentum is conserved. This means the downconverted photon pair have opposite polarizations. We will describe one of the photons as being the 'up' photon and the other photon as being the 'down' photon. One of the downconverted photons travels either the red or blue path toward D0 and the other photon travels either the red or blue path toward the prism.
There are physical waves in the aether propagating both the red and blue paths. The aether waves propagating toward D0 interact with the lens and create interference prior to reaching D0. The aether waves create interference which alters the direction the photon travels prior to reaching D0. There are actually two interference patterns being created at D0. One associated with the 'up' photons when they arrive at D0 and the other interference pattern associated with the 'down' photons when they arrive at D0.
Both 'up' and 'down' photons are reflected by BSa and arrive at D3. Since there is a single path toward D3 there is nothing for the wave in the aether to interfere with and there is no interference pattern and since it is not determined if it is an 'up' or 'down' photon being detected at D3 there is no way to distinguish between the photons arriving at D0 which interference pattern each photon belongs to. The same for photons reflected by BSb and arrive at D4.
Photons which pass through BSa and are reflected by BSc and arrive at D1 are either 'up' or 'down' photons but not both. If 'up' photons arrive at D1 then 'down' photons arrive at D2. The opposite occurs for photons which pass through BSb. Photons which pass through BSa and pass through BSb and arrive at D1 are all either 'up' or 'down' photons. If all 'up' photons arrive at D1 then all 'down' photons arrive at D2. Since the physical waves in the aether traveling both the red and blue paths are combined prior to D1 and D2 the aether waves create interference which alters the direction the photon travels. Since all 'up' photons arrive at one of the detectors and all 'down' photons arrive at the other an interference pattern is created which reflects back to the interference pattern both sets of photons are creating at D0.
The following experiment will provide evidence of aether displacement.
Instead of having a single beam splitter BSc have two beam splitters BSca and BScb. Replace mirror Ma with BSca and replace mirror Mb with BScb. Do not combine the red and blue paths. Have additional detectors D1a, D2a, D1b, and D2b. Have the photons reflected by and propagate through BSca be detected at D1a and D2a. Have the photons reflected by and propagate through BScb be detected at D1b and D2b. If you compare the photons detected at D1a and D1b with the photons detected at D0, the corresponding photons detected at D0 will form an interference pattern. If you compare the photons detected at D2a and D2b with the photons detected at D0, the corresponding photons detected at D0 will form an interference pattern. What is occurring is all 'up' photons are being detected at one pair of detectors, for example D1a and D1b, and all 'down' photons are being detected at the other pair of detectors, for example D2a and D2b. Interference patterns do not even need to be created in order to determine the interference patterns both sets of photons are creating at D0.
