Data Table for MiTIC series |
|
| Sensing Method | Bolometer using A-Si materials. The pixel resistance changes with temperature as it is heated or colled by the scene focussed upon it. |
| Sensor Type / Size |
ULIS 160x120 25µm pitch with heater when cold ULIS 320x240 25µm pitch with heater when cold ULIS 320x240 17µm pitch, sensor temperature control not required |
| Lens Parameters | Various f/1 lenses giving 50° field of view. Fixed focus by setting lens at build. |
| Dynamic Range / Control | 150°C in 'ambient scene' settings. Up to 1100°C in lowest gain mode. No iris, dynamic range controlled by sensor electronic settings. |
| Display | 2.7" or 3.5" colour LCD, driven direct |
| Sensitivity (MDTD) | Between 40mK and 90mK in 'ambient scene' depending on sensor and variant. |
| Power Source | 2 x LiFePO4 at 1100mAh (initial) to 1800mAh (current), initially a 2500mAh 'large battery' option was available. An accessory pack to take 'AA' cells was also available, mainly sold to Japan & S Korea. |
| Power System | Battery voltage used internally, camera ~4W depending on heater loading. |
| Video Output | Not provided explicitly, but available on 3.5" screen versions battery connection for potential battery mounted transmitters. |
| Image Processing | Bolometer sensors require calibration and also 'on the fly' blank field correction using a periodic shutter. Various algorithms to present the huge dynamic ranges of a fire scene with false colour choices. 160x120 pixel sensors scale up 2x. |
| Manufacturer Status | Second generation using the 17µm sensors continues, with repairs supported by Avon. |
| Number and Years Built | High 1000's from 2012 - date |
| Export Status | Dual use controlled under Wassenaar Arrangement unless a 9Hz limited type. |
