This dissertation considers a method for processing two-dimensional (2-D) signals (eg
imagery) by transformation to a coordinate space where the 2-D operation separates into …

The efficiency and speed of electrochromic display devices are determined primarily by the
amount of material which must be deposited to achieve the desired optical density. The best …

Laser recording and readout measurements using the photodichroic crystal KF: LiF indicate
that the material has potential as an input transducer and an adaptive spatial filter in an …

The concept of using optical processing systems such as optical correlators to analyze time-
dependent signals has existed since the late 1970's. Optical processors can support two …

A brief summary is given of the principles of operation of a laser image recorder used for
spectrum analysis. A special purpose acousto-optic modulator is an essential element of the …

The conventional falling-raster/folded-spectrum relationship is shown to be a special case of
a more general mapping of a 1-D signal and its spectrum into two dimensions. The well …

Известны оценки предельной плотности записи информации голографическим
методом, которые дают 107 дв. зн./мм2 для плоских голограмм [1] и 1010 дв. зн./мм3 …

Background: The rapid proliferation of sophisticated equipment has accelerated the trend to
automated testing procedures. Not only do such procedures largely eliminate operator bias …

A hybrid optoelectronic system for Fourier transform measurements of temporal signals is
described. The magnitude and phase of the signal transform are system outputs. High …

Holography is related to digital computers in three ways. First, it is a form of hard-copy output
usable by digital computers. Second, it can serve as the basis for new kinds of computer …
