Multiple characteristic recognition for spectrum patterns is presented, based onthe prinicples of projection transform and by using one dimension space variantcoherent optical processing system. The concentration of Mg,Cu and Fe in a so-lution has been measured, and the experimental results have been compared withthose which obtained by using inductive coupled plasma emissional spectroscopy

In this paper a real time optical processing system with a mathematical morphological new approach of optical frequency filtering for complex valued kernel structure element to implement binary image real time parallel processing is proposed.
In this method, we place both standard object and test workpiece on the input plane of optical processing system symmetrically and a sine grating which precisely shift 1/4 grating period on the spectrum plane, and we obtain the image of the subtraction of two objects on the output plane.
Some single-instruction multi-data(SIMD) flow calculations based on binary image transformation can be summed up binary image algebra(BIA) including five elementary images and three fundamental operations, It is of parallel processing characteristic which suits to optical processing.
Coherent optical processing of grating records creates moiré fringe pattern.
For variations of the transmission ratio of only 10 percent from the ideal case of 50 percent, the interference patterns produced by optical processing no longer correspond to multiplied moiré-fringe patterns.

An important problem in applied optics is the design of an optical processing system composed of a series of holographic lenses for the purpose of realizing an arbitrary transformation. In this paper, we give an iterative method of computation to resolve this problem. The convergence of the method and the problem in relation to finite dimension approximation are discussed. Some problems which emerged in the course of numerical calculation are analysed by means of several simple examples.
In this article, we discuss the properties of the generalized linear coherent optical-processing system proposed in  and , and show that the equivalent system exists. We further show that the parameter Zl is of little importance.
A new method for detection of the difference between two images is presented. In this method, the authors regard a white light speckle pattern as a random carrier for optical processing. The experiment demonstrated that it can be used to code information of images in an efficient way yielding a high degree of redundancy. The result obtained is similar to that by Frangon's modulated coherent light speckle patterns. But this method is simpler than Francon's.
