Title: Longcheng Que: Innovator in Infrared Technology

Introduction

Longcheng Que is a prominent inventor based in Sichuan, China. He has made significant contributions to the field of infrared technology, holding a total of 4 patents. His work focuses on improving the accuracy and quality of infrared imaging systems.

Latest Patents

One of his latest patents is titled "Method and system of two-point correction based on temperature substitution." This invention includes a black body related to the lens temperature arranged outside a lens, along with a first black body positioned in front of the lens of an infrared thermal camera. This setup allows for the collection of a gray value of the first black body, ensuring that its temperature matches the lens temperature. Additionally, a second black body is arranged in front of the lens to collect a gray value, with its temperature being higher than that of the lens. The two correction parameters obtained through black body calculations are highly applicable, effectively addressing image quality deterioration caused by temperature changes and significantly reducing the pot lid phenomenon due to non-uniformity. This innovation leads to accurate calculations of the corrected gray value.

Another notable patent is the "Exponential model based uncooled infrared focal plane array readout circuit." This invention comprises a first microbolometer unit and a second microbolometer unit, which are responsible for obtaining a detection signal and a reference signal. A conversion unit is connected to these microbolometer units, converting the detection and reference signals into linear forms. A subtraction unit then calculates the difference between these signals to produce a difference signal, which is integrated by an integration unit to yield an electrical signal that characterizes the infrared light signal of the object being detected.
