设计了一种基于CMOS传感器和ARM单片机的γ射线测量装置。STM32F103作为主要平台，控制对OV7670 CAMERACHIP™采集的图像进行实时在线分析，并以所需的帧速率将图像发送到LCD中。采样间隔的精度可以调节和控制。通过STM32F103对图像帧数进行调整，达到更好的监控效果。采用两种方法对CMOS传感器的图像数据进行分析。虽然CMOS传感器对γ射线的检测效率较低，但结果表明，它能够识别60co γ射线。
A setup based on CMOS sensor and ARM microcontroller is designed to measure theγ-rays. STM32F103 is used as the main platform to control real-time online analysis of the image collected by the OV7670 CAMERACHIP™ and send the image into the LCD at the desired frame rate. Accuracy of sampling interval can be regulated and controlled. The frame number of image is adjusted by STM32F103 to achieve better monitoring. Two methods are adopted to analyze the image data from the CMOS sensor. Although the CMOS sensor is of low efficiency forγ-ray detection, the results show that it is able to discriminate the60Coγ-rays.
