dc.description.abstract A proposed low frequency MTF camera system uses a cylinder lens to smear an area-modulated sinusoidal target into an irradiance-modulated sinusoidal image for the evaluation of a film's modulation transfer characteristics. The proposed system was constructed and evaluated. Resolution limits, field flatness, field sharpness, repeatability, de focus effects and system MTF were determined. The camera was tested with film and found to have an MTF value close to 1.0 for frequencies up to 10 cycles/mm at which point the function dropped off to a value of 0.2 at 30 cycles/mm. Off-axis images showed rapid degredation as a maximum MTF value of 0.05 for 30 cycles/mm was exhibited at the edges of the image field. en_US
