新型CCD磁场摄像器

CCD-Based Magnetic Field Imaging

本文介绍一种类似于光电二极管线阵扫描CCD摄像器的磁场摄像器,其中磁信号是以电流方式被收集并象普通CCD那样读出。磁摄像器采用埋入通道及CCD读出电路,使摄像器像素可以实现最佳化,其灵敏度高达109.7T,。

A linear array similar to a photodiode Line-Scan CCD, but with MOS magnetic sensors replacing the photodiode has been fabricated magnetic signals are collected as charges and readout as in a convention al CCD. The magnetic Sensor pixel exhibit sensitivities of up to 109.7%/T. The improved performance is possible of superior magnetic sensing properties resulting from buried channel conduction, and because the CCD readout allows the sensors to be optimized independently of the readout circuitry.
