What are Dead Pixels, Ghost Images and Pot Lid Effect in Infrared Imaging?Nov 14,2023This 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 Working Principle and Composition of Infrared SensorAug 5,2022Infrared 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.
FAQ
- How does the long EFL with large optics capabilities affect the DRI?
The focal length determines the field of view (FOV) of the thermal imaging camera. The longer the focal length, the smaller the FOV, which translates into more pixels across a target at a fixed range (meaning, the target angle divided by the IFOV angle).
- What can Quanhom lens control board do for you?
A good assistant method for monitoring targets in thermal imaging by IR zooming lens with thermal imaging cores especially for long-distance surveillance and homeland security
