Quanhom has always been active in international exhibitions related to thermal imaging technology.

This article will introduce several imaging phenomena that often occur in infrared imaging - dead pixels, ghost images, and the pot lid effect. And some methods to solve these defects are given, such as: non-uniformity correction, compensation, SDRAM and FLASH.

The advantage of infrared sensor engineering design plays an important role in the performance of the whole system. Infrared imaging technology with wavelengths ranging from 3 to 5 μm and 8 to 12 μm has always been the focus of the development of infrared imaging technology. Which of these two bands is superior in long-range detection? This issue has been under discussion since the 1970s, showing its importance.

Infrared sensor is one of the main functional units of infrared system. Its main task is to detect various dynamic and static targets, and transmit the detected target signals to infrared information and image processing unit for processing. So this article briefly introduces the working principle and composition of infrared sensor.

Infrared thermal imaging technology has gradually become a more mainstream technology in the past few decades. With the increasing popularity of handheld thermal imaging cameras, there is a growing awareness of the industrial benefits of this technology.

Infrared thermal imaging is an image formed by detecting infrared energy emitted by a person or object. Applications in security include fire monitoring, camouflage, and concealed target recognition, and other fields. The following is a detailed introduction for you.

Thermal imagers are widely used in many industries. This article introduces six elements of choosing infrared thermal imagers. Through this article, we hope to help your company find a high-quality infrared thermal imager that meets the needs of your applications.

While aberration graphs are good for providing an optical designer with a lens' performance, it is usually an objective criterion for the user or evaluator of the lens. The following article briefly describes the optical designer's method for determining the performance of an optical lens.
