The invention discloses an infrared imaging spectrometer. The infrared imaging spectrometer comprises a moving mirror driving apparatus, a laser interference calibration system and a moving mirror control circuit. The moving mirror driving apparatus comprises a support base, a stepping motor, a ball screw, an intersection roller guide rail and a slide block, wherein the slide block is provided with a moving stereo pyramid prism. The laser interference calibration system comprises a laser, a reflective mirror, a beam splitter mirror, a compensation mirror, a one-eighth wave plate, a right-angle reflector, a fixed solid angle mirror, a polarization beam splitting prism, a laser detector and a half-wave plate. The moving mirror control circuit comprises a controller, a detection circuit acting on orthogonal interference signals and a driving circuit connected with the stepping motor. According to the invention, the system load capacity is high, a large-volume solid angle mirror can be driven to perform heavy-loa
