Every column in sensor array work in parallel and have their own cds noise reducing circuit . the signals after fpn reducing are output from the output buffer amplifiers 传感阵列中各列感光单元的传感信号并行输出,分别由对应的相关二次采样电路进行降噪处理,去除固定模式噪声后的信号通过输出缓冲放大电路进行输出。
Cmos process is used to realize the one chip integration of the sensor array and processing circuits , which accords with the development direction of soc ( system on a chip ) and smart sensor 传感器使用标准cmos工艺制造,将传感阵列与信号处理电路集成在同一芯片上,可以实现传感器的soc集成和智能化( smartsensor )设计。
To research the power consumption of gas sensors , often the front - side of the sensor array has fabricated , the back - side of the sensor is etched to form an air gap between substrate and housing 为了研制低功耗气体传感器,在传感器阵列上表面制备完成后,从下表面腐蚀传感器芯片的基底,以造成传感器芯片和封装室之间形成一个空气夹层。
Blind beamforming ( bbf ) is concerned with the reconstruction of source signals from the outputs of a sensor array without a priori information of the direction of the desired source , relying instead on signal characteristics and array structures 盲波束形成无需知道目标波达方向等先验信息,直接利用信号、基阵自身的特性,就可从基阵的输出采样信号中恢复出期望信号。
Introduced the coefficient of sweep zone , the condition of complete coverage of circumference for the pipeline has been extensive studied for a few types of sensor carriers , such as multi sensor array , multi rotating sensor array and single sensor rotating reflector 首次引入扫描带重叠系数的概念,建立了多探头阵列式、多探头旋转式和单探头旋转反射镜式检测头的不漏检条件。
Sensor array is a group of sensors deployed in certain geometry pattern. The advantage of using a sensor array over using a single sensor lies in the factor that an array can increase the antenna gain in the direction of the signal while decreasing the gain in the directions of noise and interferences.
