As nouns the difference between refection and retection
is that refection is refection while retection is (obsolete) disclosure or detection of something concealed or retection can be (engineering) detection through a concealing layer (note: this use is somewhat specific to electrical engineering and related fields investigating the uses of t-ray sensing).
