所屬分類:MPD單光子相機(jī)
更新時間:2024-11-14
簡要描述:單光子相機(jī)SPAD+TDC相機(jī)是基于32x32智能像素,每個像素包含一個SPAD(單光子雪崩二極管)探測器和一個時間數(shù)字轉(zhuǎn)換器(TDC)。在2D /強(qiáng)度模式下,SPAD陣列每幀提供1024個“字",每個“字"6bit(即單幀光子計數(shù)動態(tài)最多64光子)。
單光子相機(jī)32x32 SPAD+TDC camera SPAD+TDC在3D深度分辨/計時模式下,SPAD陣列每幀提供1024個“字",每個“字"10bit(即單幀時間分辨低至312 ps,滿量程范圍320 ns)。幀數(shù)在burst模式下高達(dá)100kfps(即最小積分幀時間為10 us),連續(xù)模式為10kfps。
