We make a detailed study of norm retrieval. We give several classification theorems for norm retrieval and give a large number of examples to go with the theory. One consequence is a new result about Parseval frames: If a Parseval frame is divided into two subsets with spans $W_1,W_2$ and $W_1 \cap W_2=\{0\}$, then $W_1 \perp W_2$.
Associating vectors in $\CC^n$ with rank 2 projections in $\RR^{2n}$: with applications
nPhase retrieval by projections in R^2 requires 2n-2 projections
