Global Sensor Technology / GSTiR Infrared Detectors and Thermal Camera Cores

Architecture of uncooled VOx microbolometers and WLP technology

Uncooled infrared detectors manufactured by Global Sensor Technology / GSTiR rely on vanadium oxide VOx microbolometer focal plane arrays.

This semiconductor compound exhibits a superior temperature coefficient of resistance TCR, providing dependable thermal flux capture within the 8 to 14 um waveband.

Advanced wafer level packaging WLP enables forming high vacuum isolation directly around 12 um pixel structures during wafer fabrication.

Eliminating traditional bulky metal ceramic housings cuts detector unit weight by sixty percent while boosting shock tolerance during industrial machinery operation.

Shutterless focal plane calibration technology in iSE612 cores

The miniature infrared core Global Sensor Technology / GSTiR iSE612 utilizes a shutterless thermodynamic compensation architecture.

In conventional thermal cameras, a moving electromechanical shutter blade periodically blocks the optical path to refresh dark current offsets, resulting in frozen video frames and audible clicks.

In the iSE612 core, continuous digital signal algorithms constantly evaluate focal plane thermal drift through substrate thermistors. This design eliminates video interruptions at 50 Hz frame rates, guaranteeing continuous thermal monitoring of rotating shafts without dropped frames.

Hardware image processing via proprietary ASIC chips in COIN cores

Compact modules of the COIN612 and COIN417 series by Global Sensor Technology / GSTiR incorporate a specialized application specific integrated circuit ASIC designed in house. The processing silicon executes a full preliminary thermal stream filtering routine directly in hardware.

Non uniformity correction NUC algorithms eliminate fixed pattern noise across detector pixels. Digital detail enhancement DDE sharpens low contrast target boundaries across wide scene dynamic ranges.

Dedicated hardware processing reduces module electrical power draw, preventing internal thermal buildup in the sensor housing.

Radiometric temperature calibration and diagnostics in PLUG cores

Industrial radiometric measurement modules PLUG612R Global Sensor Technology / GSTiR are calibrated for non contact temperature verification with high accuracy. Internal firmware converts received infrared flux density at each individual pixel into absolute temperature values.

Built in calibration matrices compensate for target surface emissivity, inspection distance, and surrounding ambient air conditions.

Plant engineers can define dynamic monitoring areas, isotherms, and automated hot spot tracking points to identify elevated heat levels on bearings and high voltage busbar connections.

Cooled mid wave MCT sensors equipped with integrated Stirling coolers

High sensitivity mid wave sensors of the C615M series by Global Sensor Technology / GSTiR operate in the 3.7 to 4.8 um spectral band based on mercury cadmium telluride MCT alloys.

To minimize internal thermal noise, the semiconductor sensor array is housed inside a vacuum metal dewar and chilled down to cryogenic 77 Kelvin temperatures by an integrated closed cycle rotary Stirling cooler.

This configuration yields thermal sensitivity NETD below 15 millikelvins, facilitating precise thermal diagnostics and optical gas imaging of volatile hydrocarbon emissions along pipelines.

Optical matching and precision alignment of germanium objective lenses

Dependable operation of electro optical thermal cores by Global Sensor Technology / GSTiR requires correct pairing and mechanical alignment of infrared lenses.

Optical elements are ground from high purity monocrystalline germanium Ge with anti reflection and durable diamond like carbon DLC thin film coatings. An athermal mechanical lens barrel compensates for refractive index shifts caused by factory floor ambient temperature changes.

Standardized mounting threads ensure stable focal alignment, while positive lock rings prevent unintended lens displacement.
