The invention discloses a dislocation image-enhancing thermal imaging sensor including a dislocation pixel array for acquiring image information; a readout circuit for reading a figure signal and performing signal amplification and noise filtering; an analog digital conversion circuit ADC for converting the analog signal read by the readout circuit into a digital signal, a digital signal processor DSP for analyzing and processing the digital signal, a micro-controller MCU for performing instruction issuing, intelligent system control, and calculation and analysis; an interface circuit for outputting the signal calculated, analyzed, and processed by the MCU, wherein the readout circuit includes a preamplifier, a low-pass filter and a correlated double sampling circuit. The correlated double sampling circuit is applied to a thermal imaging sensor, facilitates the elimination of the reset noise interference, suppresses the low-frequency noise, and can substantially improve the signal to noise ratio and signal detection precision. By means of honeycomb-shaped or rhombus pixel staggered arrangement, the resolution of the thermal imaging sensor can be greatly improved.
