Abstract

The invention discloses an X-ray detector which comprises an X ray source, a detector, a detection platform, a protective bin, a processing controller and a polarization dimming device, wherein the polarization dimming device comprises a phase selector, an intensity selector and a driving device; the phase selector and the intensity selector are sequentially arranged in front of the X ray source along the emitting direction of X ray; the intensity selector is arranged on the driving device; the driving device is connected with the processing controller; the polarization dimming device is arranged in a protective bin body. The X-ray detector is provided with the processing controller and the polarization dimming device, so that the exposure dose of a target radiation area can be controlled by the X-ray detector in a selective way, the control accuracy and the modulation accuracy of the ray exposure dose can be improved, and the safety of the X-ray detector is further improved.

Description

[0001] technical field [0002] The invention relates to a perspective detection device, in particular to an X-ray detector. Background technique [0003] X-rays are electromagnetic radiation with a wavelength between ultraviolet rays and gamma rays. Effects such as photosensitive film and air ionization. [0004] The wavelength range of X-rays is between 0.01 nanometers and 10 nanometers (corresponding to the frequency range of 30PHz to 30EHz), and it has wave-particle duality. The energy of electromagnetic waves is delivered in the form of photons (wave packets). When an X-ray photon collides with an atom, the atom can absorb the energy, and the electron in the atom can jump to a higher electronic orbital state. When the energy of a single photon is high enough (greater than the ionization energy of its electron), the atom can be ionized. In general, larger atoms have a greater chance of absorbing X-ray photons. Human soft tissues are composed of finer atoms and bo...
