TABI-1800 Industry’s widest-array, internally cooled broadband thermal imager

The TABI-1800 is a thermal broadband imager which follows the same philosophy as the TABI-320 while offering new technologies which improve sensitivity and increase the swath from 320 pixels to 1800 pixels.

TABI-1800 has excellent sensitivity due to its stirling cycle cooled MCT (mercury cadmium telluride) detector, allowing users to distinguish temperature differences as low as one tenth of a degree while diminishing thermal drift as compared to bolometer-based systems. This new imager’s 1800-pixel swath allows users to map large areas in a very small time frame.

features:

• Widest pixel resolution: The industry’s widest achievable pixel resolution range (10 cm to 1.25 m possible with typical unpressurized fixed-wing aircraft; ~2 cm resolution using a helicopter)
• Thermal resolving power: High thermal resolving power (0.05 degrees Celsius)
• Wide imaging array: Wide imaging array of 1800 pixels
• Custom optics: Our trademark high-performance custom optics which are truly diffraction-limited with sub-pixel optical spot size for superb focus.
• Simplified installation: Simplified installation as the controller, digital recording system, and precision GPS/IMU are all built into the sensor head.
• Spectral programming: to suit wide range of applications

Line Cost Savings vs Competing Imagers (up to 83%)

The controller and digital recording system is built into the sensor head. This simplifies its tidy installation in a standard air photo port commonly found in a wide variety of aircraft.

Applications for TABI-1800 include detection of underground tunnels, pipeline mapping, corridor mapping, heat loss surveys, and many other applications where there are even the subtlest temperature differences.

The TABI-1800 is a new breed of high-resolution airborne thermal mapper. It combines the following class-leading characteristics in a broadband thermal imaging package that can’t be matched:

Applications:

• Agriculture
• Environment
• Water Quality
• LIDAR, IFSAR
• Wildfire/Hotspot Mapping
• Defence
• Pipelines/Tunnels
• Heat Loss Mapping/Thermal Anomalies
