Embodiment Construction
[0026] see figure 1 , the present invention provides an imager, comprising a front mirror 2, a field diaphragm 3, a collimating mirror 4, an acousto-optic tunable filter 5; a front mirror 2, a field diaphragm 3, a collimating mirror 4. The acousto-optic tunable filter 5 is sequentially arranged on the same optical path; the output optical path of the acousto-optic tunable filter 5 includes first-order diffracted light (O light and E light) and zero-order diffracted light; Light (the first-order diffracted light includes O light and E light) and the zero-order diffracted light are not separated and a turning mirror 6 is set to turn the optical path; an O-light imaging system 20 is arranged on the O-light optical path turned by the turning mirror 6; The E-ray imaging system 21 is arranged on the E-light optical path turned by the turning mirror 6; the image plane of the O-light imaging system 20 and the image plane of the E-light imaging system 21 are spliced together on the p...
