In this study, the modulation transfer functions of prints, which included both mechanical and optical dot gain effects were measured from samples printed by an ink jet printer on glossy-coated, matt-coated and uncoated papers. The MTF of prints were measured from sinusoidal patterns and Fourier transforms of line spread functions from one-pixel line and step images. The MTF of print from three...

A novel technique for imaging spectroscopy is introduced. The technique makes use of an optical imaging system with a segmented aperture and intensity detector array on the imaging plane. The point spread function (PSF) of such a system can be adjusted by modifying the path lengths from the subapertures to the image plane, and the shape of the resulting point spread function will vary as a func...
