Abstract
The fractal optical modulator is the optical modulator design by using the fractal function. As well known there is an effect of aperture’s shape on the OTF signal for optical modulator. In present paper an aberration-free single annular aperture has used and the MTF characteristics responses investigate for fractal optical modulator of IR-Seeker. The annular aperture provide several frequency transmission bands within the region up to cut-off frequency. The result compared with the spatial frequency for circular shape of fractal optical modulator aperture.
