The invention provides a self-adaptive reconfigurable high dynamic range infrared detector and a control method thereof. The detector comprises a first electrode, an N-type InP layer and an intrinsic InGaAs layer, an annular P-type InP region is arranged on the outer side of the side wall of the intrinsic InGaAs layer, an oxide layer is arranged on the surface of the other side of the intrinsic InGaAs layer, and a transparent electrode is arranged on the oxide layer; and a second electrode is arranged on the P-type InP region. By applying voltage to the transparent electrode, the energy band structure and the carrier transport characteristic of the InGaAs surface can be regulated and controlled: zero bias or positive bias voltage is applied under weak light, and high sensitivity is maintained; negative bias voltage is applied under strong light, a high-concentration hole high-conductivity channel is formed on the surface of the InGaAs in an induction mode, hole collection is accelerated, and charge accumulation and an electric field shielding effect are eliminated. Therefore, linear response in a wide dynamic range is realized under the condition that external attenuation devices are not added.
