    摘要: Embodiments of the disclosed technology provide an apparatus for controlling a standing wave linear accelerator. An example standing wave linear accelerator includes an accelerating tube, a motor, and a microwave power source connected between the accelerating tube and the motor. An example apparatus includes a main processor configured to receive an envelope signal of a reflected wave signal output by the accelerating tube, determine whether an amplitude of the envelope signal is greater than an envelope threshold, and if it is determined that the amplitude of the envelope signal is less than the envelope threshold, determine whether to change a rotation direction of the motor by comparing the amplitude of the envelope signal with an envelope reference signal stored in a memory. The memory is connected to the main processor and is configured to store the envelope threshold and the envelope reference signal.

    摘要: The present disclosure provides a scanned image correction apparatus, method and a mobile scanning device. The apparatus includes an image collector, an arm swing detector, and an image processor. The image collector is configured to collect a scanned image of an object under inspection during a scanning process of scanning the object under inspection by the mobile scanning device, and determine an image parameter of the scanned image. The arm swing detector is disposed at a monitor point on a detector arm of the mobile scanning device, and configured to detect a displacement offset of the detector arm in a specified direction and build an arm swing model of the detector arm. The image processor is configured to determine a change relationship between the image parameter of the scanned image and the displacement offset of the detector arm, and correct the scanned image based on the change relationship.

    摘要: The disclosure provides a method for identifying a Raman spectrum and an electronic apparatus. The method includes steps of: measuring a Raman spectrum of a substance to be detected so as to obtain a measured spectrogram, the measured spectrogram including a series of data; extracting peak information of the measured spectrogram, the peak information including a peak intensity, a peak position and a peak area; comparing the peak information of the measured spectrogram with peak information of a prestored standard spectrogram so as to identify whether or not the peak information of the measured spectrogram matches the peak information of the standard spectrogram; and comparing, when identifying that the peak information of the measured spectrogram matches the peak information of the standard spectrogram, data of the measured spectrogram with data of the prestored standard spectrogram, so as to further identify whether or not the measured spectrogram matches the standard spectrogram.
