Abstract: We address generalized measurements of linear multimode operators and discuss some aspects relevant to constructing angle operators for arbitrary quadratic Hamiltonian systems via Weyl-ordered expansions in terms of position and momentum operators.

Keywords: quantum angle operator, generalized measurement, harmonic oscillator system, linear multimode operator, heterodyne detection.
