A setup based on CMOS sensor and ARM microcontroller is designed to measure the γ-rays.STM32F103 is used as the main platform to control realtime online analysis of the image collected by the OV7670 CAMERACHIP~(TM) 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 for γ-ray detection, the results show that it is able to discriminate the ~(60)Co γ-rays.
