The invention discloses a novel single-pawn portable chemical toxicant passive telemetering imager. The problem that the existing chemical toxicant passive telemetering imager is hard to be applied tothe real-time detection of the field environment of battlefield due to large volume, complex structure and inconvenient carrying is solved. The chemical toxicant passive telemetering imager comprisesa lobster eye lens, a dichroscope, a first visible light CCD detector, a multi-element optical component array, an infrared image intensifier, a second visible light CCD detector, an accumulator, a liquid crystal display screen, and a microprocessor; and light fiber is arranged between the infrared image intensifier and the second visible light CCD detector. The chemical toxicant passive telemetering imager is simple in structure, scientific and reasonable in structure, and convenient for use, the defect that the imager is small in light amount, low in sensitivity and unused under complex environment in the non-dispersion infrared technology is overcome, and the comprehensive performance is close to the Fourier transform infrared spectroscopy, but the size and the cost are greatly reduced; the imager disclosed by the invention has the advantages of being convenient for operation, strong in environment adaption, high in light collecting efficiency, large in field of visual, and high indirection sensitivity.
