A GUI application for Andor sCMOS, based on Qt framework.
This application is built for Andor Zyla 4.2 sCMOS (USB 3.0 version). I think it will also works for other Andor cameras, if they are supported by Andor SDK3.
The original purpose of writing this is making sCMOS cooperate with Horiba's monochromator. It's a normal camera controlling application, integrated with a simple remote call server, which can be use to communicate with other instruments' controlling application.
It can
- modify camera properties
- snap images
- live preview
- open a server, wait for remote calls
First, make sure the camera can be found by you computer. Open the Device Manager of Windows, check if the camera is properly recognized. If not, install camera's driver which is included in Andor SDK (c++, LabVIEW, MATLAB).
Download the latest pre-build package for windows, then install it.
Power up the camera, connect to computer. (NOTE: If your camera is USB 3.0 version, make sure the cable and the USB port is capable with USB 3.0. Or, you may suffer a lot of trouble.)
Open the application, connect the camera.
You can modify the properties by click on the property browser. Press Enter to commit changes.
Click Snap to capture an image. Click Live to open a live preview. You can save current image.
If some instruments want the camera to capture a series of images at the right moment, you can use the remote call server.
It works like a software external trigger. Sends a request to the server, then the server will control the camera to do the things.
For example, The monochromator expects the camera to capture a image after each movement of the center wavelength. Integrate monochromator's controlling program with a TCP socket client. Every time monochromator has adjusted the center wavelength, send a request to the remote call server through socket. The server will reply when it has done the jobs which the monochromator requested. Then the monochromator can move to next center wavelength and send next request.
More details about remote call can be found in the following section.
- Qt
- Andor SDK3
- openCV
Follow the Qt wiki How to setup Qt and openCV on Windows to setup Qt and openCV. Install Andor SDK3.
Open .pro file with Qt Creator, you may need to configure the project. check if the include/lib paths in .pro file are correct.
Run qmake (Build > Run qmake) every time you modify the .pro file.
Build the project (Build > Build Project).
The idea is from RPC server, but is much simpler. It's based on TCP socket. When the server receives a request, it will keep the socket connection, until the job is done and send an 'ack' message. Currently, 'ack' message is always "0", maybe later it will be implemented to carry more information.
Request format:
i:<id>;m:<method>;p:[param1,param2,...]
id: a unique string for identification. (currently has no effect)method: method/function name provided by remote call serverparamN: parameters of method/function
Ack format:
0
Method: snap
Parameters:
filename: File basename for image saving.
metadata: Extra information.
