Passive Fourier Transform Infrared Remote Sensing Analyzer
Passive Fourier Transform Infrared Remote Sensing Analyzer operates across a 600 to 1500 cm⁻¹ spectral range with 4 cm⁻¹ standard resolution and 40 kHz scanning speed. The main unit measures 520 mm × 400 mm × 230 mm at under 18 kg, while the gimbal assembly weighs less than 18 kg at 300 mm × 260 mm × 320 mm. A Stirling compressor-cooled MCT detector pairs with a domestic ZnSe beam splitter and 2x magnification telescope offering 10 mrad full field of view. The gimbal rotates 360° horizontally and -10° to +50° vertically at adjustable speeds from 0.1° to 8° per second with positioning accuracy below ±0.01°.
Detection sensitivity reaches 50 ppm·m for nitrogen at one-meter cloud thickness with 2°C temperature differential. The system identifies chemical warfare agents including sarin, soman, Lewisite, and mustard gas alongside 40+ industrial toxins such as ammonia, sulfur dioxide, ethanol, acetone, and trichloroethylene. An integrated visible camera provides 1920×1080 resolution with 8x zoom and 59.6° field of view at 0.4 to 0.9 µm wavelength. The unit requires no external excitation sources, enabling full-darkness operations during nighttime monitoring missions.
Emergency response teams deploy the Passive FTIR Sensing Analyzer for chemical accident assessments at industrial sites. Military forces mount it on vehicles, ships, helicopters, and drones for mobile threat detection across five-kilometer scanning radii. Environmental monitoring agencies track pollutant emissions from production facilities and analyze concentration gradients during leak incidents.
Tactical Supply Pakistan supplies this imaging analyzer to agencies requiring standoff detection capabilities that map toxic cloud distribution patterns without entering contaminated zones.
Can this system operate effectively during complete darkness?
Yes, passive FTIR technology detects thermal emissions from gas clouds without external illumination, maintaining full analytical capability throughout night operations.
