The control serial port of the upper computer for the infrared movement is “SSCOM_INF_EN English new version.exe” (referred to as the control serial port). Double-clicking the file will generate the control interface.

The software operation steps are:

1) : Correctly select the port number of the serial port (depending on the computer being used), set the baud rate (115200 BPS), and then click “Open Serial Port”. After the correct Settings, the control serial port interface changes to the one shown in the figure on the right. The green box in the figure turns green, indicating that the control serial port is working properly.

2) Introduction to the control serial interface, with the red box representing quick commands, users can control the MWIR1503MCL infrared movement by clicking the buttons inside the box.

Q1 : What is Mid-Wave Infrared (MWIR) technology?

MWIR technology is an infrared imaging technology that operates in the 3–5 μm waveband. It is widely used in advanced defense imaging systems, providing critical capabilities such as surveillance, target detection, and data collection.

Q2 : What are the advantages of MWIR over LWIR (Long-Wave Infrared)?

Under certain conditions, MWIR cameras can detect objects up to approximately 2.5 times farther than LWIR cameras. Additionally, MWIR is less sensitive to atmospheric effects, making it particularly effective in environments with good visibility and favorable weather conditions.

Q3 : What are the characteristics of MWIR in target detection?

MWIR is highly sensitive to temperature differences and excels at detecting high-temperature targets such as engines or missile plumes. Its strong thermal contrast enhances imaging performance, making it well‑suited for precise detection in highly dynamic scenarios.
