Fully automated measurement of the modulation transfer function of charge-coupled devices above the Nyquist frequency.
The charge-coupled devices used in electron microscopy are coated with a scintillating crystal that gives rise to a severe modulation transfer function (MTF). Exact knowledge of the MTF is imperative for a good correspondence between image simulation and experiment. We present a practical method to measure the MTF above the Nyquist frequency from the beam blocker's shadow image. The image proce...
متن کاملCoded aperture imaging: the modulation transfer function for uniformly redundant arrays.
Coded aperture imaging uses many pinholes to increase the SNR for intrinsically weak sources when the radiation can be neither reflected nor refracted. Effectively, the signal is multiplexed onto an image and then decoded, often by computer, to form a reconstructed image. We derive the modulation transfer function (MTF) of such a system employing uniformly redundant arrays (URA). We show that t...
متن کاملUnsupervised frequency tracking beyond the Nyquist frequency using Markov chains
This paper deals with the estimation of a sequence of frequencies from a corresponding sequence of signals. This problem arises in fields such as Doppler imaging, where its specificity is twofold. First, only short noisy data records are available (typically four sample long), and experimental constraints may cause spectral aliasing so that measurements provide unreliable, ambiguous information...
متن کاملMultirate Adaptive Compensation of Uncertain Resonances Beyond the Nyquist Frequency
In this paper, an add-on multirate adaptive control scheme is proposed for compensation of uncertain mechanical resonant modes beyond the Nyquist frequency in mechatronic systems. A polynomial transformation technique is applied to obtain the mixedrate model of the control system that is suitable for multirate adaptive control design. To preserve the performance of the pre-designed nominal cont...
متن کاملDisturbance Suppression beyond Nyquist Frequency in Hard Disk Drives
In conventional hard disk drives, a control system compensates for vibration in which the frequency is higher than the Nyquist frequency by using a multi-rate filter that decreases the gain above the Nyquist frequency. However, such a control system can only avoid instability and cannot suppress disturbances above the Nyquist frequency. In response to this problem, a control system design metho...
