The configuration of the system for photochemical reaction imaging
The system is placed in a compact case that is effectively an intraoral camera with a built-in emitter. The camera field of view at a working distance from the object (about 15 mm) is 1 cm2. The construction of the system provides overlapping between the camera field of view and the area excited by diagnostic irradiation. The power is supplied to the whole system via USB.

The operating procedure of the photochemical reaction imaging system
An example of an image obtained using the photochemical reaction imaging system is shown in Fig. 2. It is a picture of the spatial fluorescence distribution for a Photoditazin solution coated on a sheet of paper. The brightness value for each pixel of the image carries information on the photoluminescence intensity of Photoditazin in the respective points of the paper surface. In this adenosine deaminase inhibitor experiment the Photoditazin solution was unevenly distributed over the surface of the paper, which is why areas with different brightness can be seen in Fig. 2. The brightest areas of the image correspond to the maximum Photoditazin concentration.

Conclusion

Acknowledgment

Solving inverse problems of charged particle dynamics in electrical and magnetic fields is a powerful tool for designing new corpuscular optics systems with the desired characteristics. Some of the noteworthy results obtained through this approach are the construction of an energy-analyzing system with ideal focusing in the symmetry plane , and the creation of mass-separating systems with ideal spatial and temporal beam focusing . Even though a substantial range of analytical means has been accumulated this far (see, for example, Monographs ), not many inverse corpuscular optics problems have been solved , while obtaining and analyzing new solutions, and finding applications for them is without doubt of great interest and relevance.
The fields with a symmetry plane discussed in this study may serve as basis for constructing modern devices for analysis of variance of charged-particle beams by energy. The concept of such devices is in discriminating the particles by energy and concentrating them by other parameters (in particular, by starting angle). Recently, a number of monographs and papers [–] have been published developing the theoretical foundations for this type of devices, which attests to the current interest in energy analyzers.
Polytechnic University professor Yu. K. Golikov suggested the following approach to setting the problem of searching for symmetrical electrostatic structures with the predetermined properties . A plane is taken that is then associated with the system\'s symmetry plane. The potential depends only on the coordinate , the dependence () is monotonic and provides the deceleration of a charged particle moving along the positive direction of the axis. The particle drifts along the axis, since the force is absent along the coordinate. We assume below that a particle with the dimensionless energy (the dimensionless variables are introduced according to ) starts from the origin of coordinates at an angle (0<
