Uncooled Thermal Imaging Detectors: Is VoX Or α-Si Better?
2023-06-09
As the core component of thermal imaging, the detector is not an exaggeration to put it in the first place when purchasing. The mainstream materials of the heat-sensitive element of the uncooled infrared detector are mainly vanadium oxide (VoX) and amorphous silicon (α-Si).
The uncooled thermal imager using vanadium oxide focal plane detector is a relatively new type of thermal imager in China. Compared with polysilicon, vanadium oxide material focal plane detector has better image quality and sensitivity, which can better meet different application requirements. In the past, thermal imaging cameras produced in China mainly used polysilicon bolometers. In short, the main advantage of vanadium oxide detectors is higher photoelectric conversion efficiency for infrared light, higher signal-to-noise ratio and strong light protection ability than polysilicon detectors. The vanadium oxide detector has good temperature stability, long life and small temperature drift.
The detectors of Handheld Multifunctional Thermal Binoculars produced by our company are all made of VOX. The latest models of Handheld Multifunctional Thermal Binoculars developed by our company are MH-N/MH-TN6100/HTLR-6103M/MH-900.
Take MH-900 as an example
MH-900 is a handheld infrared detection device with various functions and uses. It adopts a system composed of a variety of advanced sensors, signal processing circuits and optical components. It can observe and detect targets all day and night.
The MH-900 is equipped with a 640×512 long-wave uncooled infrared detector, which provides high-quality high-resolution infrared images. It can search and detect targets in complete darkness, haze and fireworks, thus helping users to find and compare hidden targets.
In addition, MH-900 also integrates long-distance eye-safe laser ranging, GPS/BDII and digital electronic compass, which can help users locate geographic information such as observation position and target orientation. MH-900 also has professional functions and simple control, which not only reduces the number and weight of reconnaissance equipment carried by users, but also improves the ability to comprehensively process various information data in a timely manner while meeting the needs of different users.
