Dynamic　characteristics　play　a　crucial　role　in　evaluating　the　performance　of　weight　sensors　and　are　essential　for　achieving　fast　and　accurate　weight　measurements.　This　study　focuses　on　a　weight　sensor　based　on　optical　coherence　displacement.　Using　finite　element　analysis,　the　sensor　was　numerically　simulated.　Frequency　domain　and　time　domain　dynamic　response　characteristics　were　explored　through　harmonic　response　analysis　and　transient　dynamic　analysis.　The　superior　dynamic　performance　and　reduced　conditioning　time　of　the　non-contact　optical　coherence-based　displacement　weight　sensor　were　confirmed　via　a　negative　step　response　experiment　that　compared　the　proposed　sensing　method　to　strain　sensing.　Moreover,　dynamic　performance　metrics　for　the　optical　coherence　displacement-type　weight　sensor　were　determined.　Ultimately,　the　sensor＇s　dynamic　performance　was　enhanced　using　the　pole-zero　placement　method,　decreasing　the　overshoot　to　4.72%　and　reducing　the　response　time　to　0.0132　s.　These　enhancements　broaden　the　sensor＇s　operational　bandwidth　and　amplify　its　dynamic　response　capabilities.
