abstract = {<p style="text-align: justify;">We study the norm retrieval by projections on an infinite-dimensional
Hilbert space $H.$ Let $\{e_i\}_{i∈I}$ be an orthonormal basis in $H$ and $W_i = \{e_i\}^⊥$ for all $i ∈ I.$ We show that $\{W_i\}_{i∈I}$ does norm retrieval if and only if $I$ is
an infinite subset of $N.$ We also give some properties of norm retrieval by
projections.</p>},
