A modulation transfer function (MTF) measurement technique suitable for large-format, small-pixel detector characterization has been investigated, using a volume interference grating as a test image instead of the bar or sine wave target images normally used.Abstract:
A modulation transfer function (MTF) measurement technique suitable for large-format, small-pixel detector characterization has been investigated. A volume interference grating is used as a test image instead of the bar or sine wave target images normally used. This technique permits a high-contrast, large-area, sinusoidal intensity distribution to illuminate the device being tested, avoiding the need to deconvolve raw data with imaging system characteristics. A high-confidence MTF result at spatial frequencies near 200 cycles/mm is obtained. We present results at several visible light wavelengths with a 6.8-micron-pixel CCD. Pixel response functions are derived from the MTF results.read more

Off-axis optical quality and retinal sampling in the human eye
TL;DR: New measurements obtained are reported with conditions chosen instead to optimize retinal image quality: paralyzed accommodation, used a 3 mm pupil, and corrected defocus and oblique astigmatism at each retinal location.

Double-pass and interferometric measures of the optical quality of the eye.
TL;DR: On the basis of the interferometric method, a new estimate of the monochromatic MTF of the eye is proposed, suggesting that much of the reflected light is confined within individual cones throughout its double pass through the receptor layer.

Interlacing in charge-coupled imaging devices
TL;DR: In this paper, an efficient way to achieve a 2:1 readout from charge-coupled area imaging devices of the frame transfer type is described, where the resolution cells of the device are elongated in the vertical dimension to extend across the distance corresponding to two scanning lines in the display.
