Double-flying line multi-slit scanning backscatter planar imaging, stereoscopic imaging and self-scanning imaging device

Disclosed is a scanning device using radiation beam for backscatter imaging. The scanning device includes a radiation source; a stationary shield plate and a rotary shield body positioned respectively between the radiation source and the subject to be scanned, wherein the stationary shield plate is fixed relative to the radiation source, and the rotary shield body is rotatable relative to the stationary shield plate. The ray passing area permitting the rays from the radiation source to pass through the stationary shield plate is provided on the stationary shield plate, and ray incidence area and ray exit area are respectively provided on the rotary shield body. During the process of the rotating and scanning of the rotary shield body, the ray passing area of the stationary shield plate intersects consecutively with the ray incidence area and the ray exit area of the rotary shield body to form scanning collimation holes. Further, a scanning method using radiation beam for backscatter imaging is also provided.

Device for testing explosive with backscatter technology

The invention relates to an imaging system with the function of X-ray backscatter and tomoscan, which includes X-actinogen, a monitoring and scanning machine, a revolving means, a driving means and processing circuit. The monitoring and scanning machine is arranged on the front end of the X-actinogen, which comprises a collimating element, a backscattering detector and a transmission detector. The backscattering detector is positioned at the front of the collimating element while the transmission detector is arranged opposite the backscattering detector. The invention provides an imaging system with the function of X-ray backscatter and tomoscan for detecting and scanning The system distinguishes different material by three-dimension graphics and backscatter image processing after backscattering and tomoscan, thus enhancing the ability of assessment dynamite and detonator.

Image-forming system with X-ray backscattering and tomography scanning

The invention discloses a device of flying dots formation in ray imaging and the method. The device mainly includes a collimating element and a flywheel. The flywheel includes at least one contour groove. The contour groove keeps vertical to the projection on the flywheel all the time however rotates and the upper contour of the contour groove keeps consistent with the incident ray through the uppermost area of the contour groove. The lower contour keeps consistent with the incident ray through the inferior part of the contour groove. The formation of flying dots of the device is that the ray field produced by active source shapes ray contour through contour groove of the flywheel and forms ray bunches through the finedraw collimating element, then flying dots formed after the ray bunches radiate on the sample to be detected. The flying dots of the device are regular in shape, uniform in size, clear in image and with no penumbra.

Flying spot forming device and method used for ray image-forming

The utility model discloses an automatic lead mould manufacturing device which comprises a mould sleeve system, a molten lead pouring system and demoulding system, wherein the mould sleeve system comprises a lead making mould sleeve which has a hollow structure; the molten lead pouring system comprises a lead melting furnace, a pouring pipe, a pouring control valve and a liquid level sensor, wherein the liquid level sensor monitors the liquid level of the molten lead in the lead making mould sleeve and sends a signal for driving the pouring control valve to open and close; the demoulding system comprises a demoulding motor and a demoulding push rod, wherein the demoulding push rod is driven by the demoulding motor to move up and down to knock the forming lead mould inside the lead making mould sleeve. The automatic lead mould manufacturing device integrates the prior lead mould making process and manufacturing lead moulds with one set of device, which reduces the labor intensity of workers manufacturing the lead moulds, improves the accuracy and efficiency of the lead mould manufacturing and well protects the cleanness of the operation environment and the health of operators.
