Under different spatial button resolution, the quantum detection efficiency of the X-ray detector varies. The representation method of the quantum detection efficiency is usually expressed by the ratio of the square of the output signal to noise ratio to the square of the input signal to noise ratio.
The quantum detection efficiency mainly reflects the density resolution of the flat plate detector.Since the conversion efficiency of photoelectric signals has an impact on the efficiency of quantum detection, the structure of photoelectric conversion affects the efficiency of quantum detection.
Since the direct conversion mode of metal detectorX relies on the electron hole pair of amorphous selenium, its quantum detection efficiency depends on the ability of amorphous selenium to generate charge.
Newheek metal detector can be divided into wired type and wireless type, which can meet your different procurement requirements.
