through the collimator 48 towards the mirror unit 16 as image a the scintillation system 42 is located between the slide 40 and the assembly 44 the scintillation system 42 generally comprises a scintillation wheel or disk 52 and a driver 54 energy from the energy source 38 passes through the target slide 40 and is transformed into a projected image of the target the projected image from the slide passes through the scintillation wheel 52 which adds the scintillation effect of an image traveling through the atmosphere the scintillated image then enters the assembly 44 the scintillation system 42 and its operation is described in detail further below an alternate embodiment of the present invention could comprise the scintillation medium being located between the energy source 38 and the target slide 40 the second source group 20 generally comprises a second energy source 56 a second slide 58 and a second combined lens and collimator assembly 60 the source 56 is a heat source adapted to generate infrared energy and project it towards the slide 58 the slide 58 is a low resolution photographic slide of multiple targets and or clutter that might be viewed by a seeker head traveling through the atmosphere or viewed from space the assembly 60 generally comprises a zoom lens 62 a zoom.
