滨松开发了一种图像传感器,结合了 TDI-CCD 的优势,即使在高速成像期间也能确保图像的足够辉度,同时具有 CMOS 读出电路的优点,可实现高速行速率和数字输出。
虽然传统的 TDI-CCD 图像传感器能够实现高灵敏度、高速成像,但是鉴于它们使用模拟输出,客户有必要添加信号处理电路。我们新开发的 S14810 和 S14813 使用 CMOS 读出电路用于数字输出,简化了外部电路设计,使产品更易于使用。
我们还提供定制设计,例如增加 TDI-CCD 像素数量,或增加列并行读出的列数,以提高行速率。
S14810/S14813 规格
在 S14813 中,我们使用滨松多年来开发的受光面技术,以实现世界级的紫外灵敏度和抗紫外线性能。由于 TDI 方法捕获高速移动物体的图像,设备上的入射光量通常较低,因此必须具有更高的灵敏度。
我们还提供 S14810,当不需要紫外线灵敏度且设备入射光量足够时,它比 S14813 更加平价实惠。
TDI(时间延迟积分)是 CCD 的一种特殊读出方法。在 CCD 中,每行中的信号电荷在电荷读出期间垂直传输。通过将此传输时间与对象的时刻同步,它能够集成等于 CCD 像素垂直级数的曝光。这种方法称为 TDI,能够以高速和高灵敏度对移动物体进行成像。
