LabVIEW-based EMCCD camera data acquisition driving method

Abstract

The invention discloses a LabVIEW-based EMCCD camera data acquisition driving method. The LabVIEW-based EMCCD camera data acquisition driving method comprises the steps: firstly invoking a camera internal function to initialize a camera; setting the mode of each module of the camera; computing relative photography parameters of the camera, thereby obtaining the pixel size of a camera detector; developing an image storage array; then, setting a For cycle to perform image acquisition and implement a pausing function; finally, invoking a ShutDown command function to release the memory space. According to the LabVIEW-based EMCCD camera data acquisition driving method, a great deal of unnecessary function invocation is reduced, so that a program is greatly simplified; the camera does not utilize only Solis software of the Andor company any more, but can combine other LabVIEW-driving hardware to achieve different purposes of data acquisition, image processing and the like, thereby overcoming a defect that the Solis software cannot be connected with the LabVIEW in use; the use range is wider; besides, purposes that the number of photographed frames of the camera is freely controlled and details of a current single-frame image can be viewed under the condition that the photography of the camera is not stopped but pauses are achieved.

Description

technical field [0001] The invention belongs to the image acquisition technology of an electron multiplication CCD imaging system, in particular to a data acquisition and driving method of an EMCCD camera based on LabVIEW. Background technique [0002] With the rapid development of scientific information technology, the world has entered the era of photons, and the means for people to obtain information are expanding to wider fields such as different wave bands. As the most direct and effective information, image information has been widely valued. How to obtain clearer and more accurate image information has become an important research content. Low-light imaging technology conforms to this development trend and has become one of the emerging high-tech technologies for both military and civilian purposes that developed countries in the world are vigorously developing. [0003] Electron Multiplication Charge Coupled Device (EMCCD) is a high-end photodetection product with ...

AI Technical Summary

Problems solved by technology

However, the existing electronic multiplier CCD cameras have inevitable defects: the data readout method is limited and cannot be connected with other hardware, resulting in a very limited range of use

[0005] Although Andor company provides Solis software, which can be connected with the camera and shoot, its scope of use is limited to the software itself, and it cannot be combined with subsequent data processing hardware. It can only take pictures, has a single function, and has no real-time performance.

Secondly, when the camera fails, it is impossible to know the cause of the failure conveniently

In addition, when the experiment is based on LabVIEW, it is impossible to connect to it and collect data, and it is impossible to realize the functions of controlling the number of shooting frames and pausing to view, and LabVIEW is a bridge connecting the hardware of the imaging system and image processing system, so it has considerable technical flaws
