Problems solved by technology

Currently the most widely used ion image collection device is the Imager series produced by Lavision Corporation. The cost of this set of collection devices is very expensive, and the camera and computer use optical fibers to transmit signals, which is easily damaged; in addition, for the collection of pictures and the collected Image storage formats are very limited

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the examples.

[0023] Such as figure 1 , 2 Shown, the present invention comprises the following steps:

[0024] Step 1. Connect the ion lens device with the fluorescent screen through a connecting cylinder, and let the charged particles emitted by the ion lens device shoot onto the fluorescent screen. A digital camera with a lens adjusts the focal length so that the resolution of the image collected by the camera is the best; the lens of the digital camera faces the fluorescent screen so that the digital camera collects the fluorescent pictures emitted on the fluorescent screen.

[0025] Step 2. Fix the digital camera with the adjusted focal length on the black-plated bracket, and seal the connection with black material to reduce the influence of external light as much as possible.

[0026] Step 3. The CCD camera is connected to the trigger through the signal line to realize external...

Abstract

The invention relates to a method for collecting ion images, comprising the following steps: a digital camera is connected to a computer through a network cable; the computer finds the camera according to the IP address of the digital camera, and controls the digital camera to collect images according to the set image capture frequency; the pictures are transmitted through the network cable When the computer has a cache area, the computer performs event-counting acquisition processing on the images in the buffer area; and accumulates the processed images together, and stops collecting until the set time is reached; stores the accumulated images into the specified file, And stored in various forms of files. The invention can achieve the same effect as commercial professional acquisition equipment by using a low-cost ordinary digital camera; realizes low-cost ion image acquisition, and can save the purchase time and cost of the instrument.

Description

technical field [0001] The invention relates to an ion image collection method, in particular to a collection method for realizing three-dimensional spatial distribution information of ion signals. Background technique [0002] In the research field of molecular reaction dynamics, only when the internal energy and velocity of all products are clear can the dynamic information of the molecular reaction process be fully understood, so it is often necessary to measure the velocity distribution and angular distribution of the product at the same time. The ion imaging method can obtain the velocity distribution, internal energy distribution and angle distribution of the whole molecular reaction process by measuring the three-dimensional velocity distribution of a certain product after state selection. Due to its high-sensitivity detection and high-resolution characteristics, ion imaging technology has been widely used in the field of molecular reaction dynamics. Currently the mo...
