Remember that a sampled imager is not shiftinvariant. That means that, as the sensor is panned across the scene, the displayed image changes depending on sample phase. 7. Eye MTF can be an important factor in limiting the visibility of both the transfer response and spurious response. When analyzing a sensor and display system, Pix(ξ) should generally include the eye MTF. It should be remembered that the effect of eye MTF depends on system magnification. The frequency used when calculating eye MTF is the object space frequency divided by system magnification.
Each of the components in the system contributes to the blurring of the scene. The blur attributed to a component may be comprised of more than one physical effect. For example, the optical blur is a combination of the diffraction and aberration effects of the optical system. 11) The Fourier transform of the system impulse response is called the transfer function of the system. Since a convolution in the spatial domain is a product in the frequency domain: O(ξ, η) = I (ξ, η) H atm (ξ, η) H optics (ξ, η) H det (ξ, η) H elec (ξ, η) H disp (ξ, η) H eye (ξ, η) .
Also, remember that ν is 1/X (the sample spacing). 22) n =−∞ ∞ G (ξ) = R (ξ) F (ξ − n ν )e jnφ n =−∞ where φ ≡ sample phase in radians. 18. The presample image spectrum is replicated at every integer multiple of the sample frequency. 18(a). 18(a) is the display MTF. The Fourier transform of the image is found by multiplying the replicated spectrum by the display MTF. 18(b). The phase of each adjacent replica changes by the sample phase. If the display MTF does not filter out the replicas of F(ξ) adjacent to the baseband, then the displayed image will vary with sample phase.
