Embodiment Construction

[0044]The present invention will be further described in detail below with reference to the accompanying drawings and examples, but the scope of the invention is not limited to the content.

[0045]An image-aligned adjustment and inspection system applied to a micro-light image reinforcerator, including: CCD camera 3, light source 7, gas control machine 12, valve 8, and regulator power supply 11. The CCD camera 3 is connected to the computer 13, and the crossline of the potting mold or the inspection mold can be observed in real time by computer 13 for calibration or testing. The light source 7 provides a light source for a micro-image enhancer on a potting mold or a test mold for a CCD camera 3. The gas control machine 12 is connected to the valve 8 to provide pneumatic power of the pneumatic shaft 5 through the valve 8. The regulator power source 11 is a gas controller 12 powered by the required power.

[0046]The system also includes a potting mold that is equipped with an unmovable mi...

Abstract

The invention discloses an image alignment adjustment and inspection method applied to a low-light-level image intensifier, wherein the cathode input center and the shell center of an assembled low-light-level image intensifier are effectively controlled by using an image alignment adjustment system while the encapsulated low-light-level image intensifier can be effectively inspected. The method comprises the following steps: assembling an encapsulation mold or an inspection mold, opening an image alignment adjustment and inspection device, adjusting a gas cylinder pressure regulating valve and a pressure gauge, introducing gas into the encapsulation mold or the inspection mold, placing the encapsulation mold or the inspection mold above a lower contact ring, closing the valve to enable an upper contact ring to fall to the top end of the encapsulation mold or the inspection mold, adjusting a focusing adjusting knob and a lifting knob, focusing the light spot generated by a camera on the cross curve of the potting mold or the inspection mold, coinciding the center of the cross curve with the light spot, observing the deviation condition of the center of the cross curve and the light spot, if the deviation exceeds the specification, adjusting a knurled screw for alignment, then potting, and carrying out other steps. According to the invention, the yield and the working efficiency of the image intensifier are improved.

Description

Technical field[0001]The present invention relates to the field of micro-light image reinforcing assembly techniques and inspection techniques, and more particularly to a photographic alignment adjustment and test method for micro-light image reinforcers, mainly for adjusting the inward imageless micro-light image enhancement to be potted. The cathode input center and the hous axis of the housing and the detection value of the potted micro-image enhancer image alignment value.Background technique[0002]The micro-light night vision is used as a long-term super-visual eye, closely observed, tracks and identified important combat tools, have been used by all military units such as land, sea, and empty, and is also in national security, industrial and medical hygiene. The field is widely used in the field, and the micro-light image enhancer is the core device of the micro-light night vision, and the performance parameters of the micro-light image reinforcement directly determines the tac...
