產(chǎn)品型號：
所屬分類：MPD單光子相機
更新時間：2024-11-14
簡要描述：單光子相機SPAD+TDC相機是基于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100kfps（即最小積分幀時間為10 us），連續(xù)模式為10kfps。
