| Abstract: | This paper concerns the design of long wave uncooled infrared (IR) thermal camera based on uncooled focal plane array (UFPA).The optical system of this imaging system was briefly introduced while the design of the electrical system and the crux of the technique were described in detail.The IR sensor is a 320?240 LW IRCMOS uncooled integrated microbolometer UFPA.By making use of double-reflected optical system,the image quality was improved and the aberration is reduced,and adopting new CPLD technique complete the driving of IRUFPA.In signal processing,the Nonuniformity Correction (NUC) of IRUFPA,image enhancement,contrast improvement and real-time display IR were discussed. |
| Keywords: | Microbolometer Focal plane array Uncooled Uncooled Non uniformity correction Infrared thermal camera |
