TF-Luna (ToF) 微型單點測距雷達 高精度雷射測距模組
TF-Luna (ToF) 微型單點測距雷達 產品內置多種應用環境及目標的適配演算法，可以保證在複雜環境中具有優良的測距性能。TF-Luna 基於 TOF（Time of Flight）即飛行時間原理。具體為產品週期性的向外發出近紅 外光調製波，調製波遇物體後反射。產品通過測量調製波往返相位差，得到飛行時間，再計算出 產品與被測目標之間的相對距離。
TF-Luna 的測距重複精度與測量時的信號強度值（Amp）及輸出幀率相關，Amp 越大，重 複精度越高，輸出頻率越低，重複精度越高。以測距 1σ 標準差表徵測距重複精度，下面給出了 100Hz 輸出幀率時，不同測試條件下的 1σ 標準差，僅供參考，實際標準差可能受使用環境影 響。
