Digital maps on personal devices (eg, phones) are common tools used to aid navigation.
Different types of digital maps can influence spatial knowledge acquisition, and this effect …

The slanted-edge method is commonly used for measuring the spatial frequency response
(SFR) of digital imaging systems. To investigate the intrinsic capability of the slanted-edge …

The modulation transfer function (MTF) is widely used to characterise the performance of
optical systems. Measuring it is costly and it is thus rarely available for a given lens …

Abstract 2D point spread function (PSF) is a commonly used measure to assess the quality
of various imaging systems. The most convenient way of 2D PSF measurement is taking an …

One-dimensional modulation transfer function (1-D MTF) has been generally calculated to
evaluate the image quality of optical imaging systems, such as the horizontal MTF and …

Modulation Transfer Function (MTF) is the basic tool widely used in assessing the
performance of imaging systems. The most common imaging systems employed in MTF …

Point spread function (PSF) plays an important role in evaluating the quality of optical
systems and imaging restoration. Conventional methods, which use a point-like source …

Point spread function (PSF), which is the intensity distribution of optical system impulse
response and usually acquired by imaging a single pinhole in experiment, can characterize …

We show in this paper a digital random target method for measurement of Modulation
Transfer Function and Point spread function locally in all the field of view of the instrument …
