Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0035] Relay Imaging System Embodiment
[0036] Such as figure 1 The relay imaging system shown as a whole includes two parts: one part is a telescopic optical system, and the other part is a prism optical system.
[0037] For the prism optical system, the optical parameters of the prism optical system are: entrance pupil diameter: 8mm, field of view: 24°; the working band of the prism optical system is 480nm~644nm; CCD parameters are: pixel size: 4.67μm×4.67 μm, number of pixels: 1024×768.
[0038] Such as figure 2 As shown, the imaging part of the prism optical system is composed of a prism. Aperture stop 1, prism element 2 and image surface 3 are sequentially distributed along the light transmission direction from the object side to the image side, wherein the prism 2 includes three optical surfaces ,Such as figure 2 As shown, they are the first sur...
