After measuring the MTF value curve of each lens, the Hassu lab developed a calculation method for the average value of the MTF. First, the preset focal length is used to calculate the MTF value of the lens F4, multiply by the focusing coefficient of 0.4 and 0.6 respectively to obtain the MTF value of a first-line frequency, and then multiply the average value of the 10-line/millimeter value by the focusing coefficient of 0.57, the average value of th

Every integrated environment cannot have a central control server. Let's call it SUPCON here. Today, we will introduce the Public Service (common) in the lab-Bill-davidey list) module SUPCON server.
The engineering platform is here, where SSH password-free login to all hosts in the Integrated Environment stores the management scripts.
The SSH password-free configuration is as follows:
Sudo service sshd start
Sudo chkconfig sshd on

I haven't updated my blog for a long time. Of course, some of the reasons are due to the lazy inertia caused by my vacation. The more important reason is the need for work, recently, the design and research of the content and methods of the new phase of activities have been closed, and the script of some key parts has been completed; one of the most important parts is the architecture and design of the front and back-end work of the virtual lab. Today
