To provide a movement prediction device that can highly accurately predict a movement of a flying body.SOLUTION: A movement prediction device 100 comprises: a first optical output device 220; a second optical output device 230; a light reception device 270; and a computation device 114. The first optical output device 220 is configured to output output light 310 having a spectrum component of a first light comb in which a comb interval fr is a first interval. The second optical output device 230 is configured to output reference light 340 having a spectrum component of a second optical comb in which the comb interval fr is a second interval. The light reception device 270 is configured to receive synthetic light synthesizing the output light 310, reflection light 320 having the output light 310 reflected by a rotary wing 11 of a flying body 10 and the reference light 340, and measure a distance to the rotary wing on the basis of the synthetic light. The computation device 114 is configured to calculate an amount of rotation representing a rotation speed of the rotary wing 11 on the basis of a change in measured distance, and predict a movement of the flying body 10 on the basis of a change in calculated amount of rotation.SELECTED DRAWING: Figure 1
【課題】飛行体の移動を高精度に予測できる移動予測装置を提供する。【解決手段】移動予測装置100は、第1光出力装置220と、第2光出力装置230と、受光装置270と、演算装置114とを備える。第1光出力装置220は、コム間隔frが第1間隔である第1光コムのスペクトル成分を有する出力光310を出力する。第2光出力装置230は、コム間隔frが第2間隔である第2光コムのスペクトル成分を有する参照光340を出力する。受光装置270は、出力光310と、飛行体10の回転翼11により出力光310が反射された反射光320と、参照光340とを合成した合成光を受光して、合成光に基づき回転翼までの距離を測定する。演算装置114は、測定された距離の変化に基づき回転翼11の回転速度を表す回転量を算出し、算出した回転量の変化に基づき飛行体10の移動を予測する。【選択図】図1
