Problems of the OSRP design
Choice of Ways to the Design of the OSRPs.
In the first approximation most optical systems can be considered
as the systems consisting of thin components
Every component has three main parameters P, W, C which are defined by its dimension parameters and glasses.
These functional dependences are reversible.
In the first approximation the image quality can be described by third order aberration theory.
For infinite-thin component the Seidel sums are:
The chief advantages
The chromatic sums are:
The surfaces that are used in the lens design are symbolized in the following way:
For the solution of the task of OSRP research there is possible to combine power and correction components e.g. B(0c), B(0,cnc,c)+C(аа), C(cc)+B(ac)+B(ac)+C(b0) etc. (in total 16 combinations).
· The synthesis of the basic optical system from the infinite-thin components with main parameters with addition of the components, which have the known aberration characteristics
The design of the basic RPO system on the base of the thick concentric meniscus and a power component
For this basic system the following algorithm of design was offered:
The present algorithm allows to design the base RPO systems with the following characteristics:
The scanning devices lens1:20 10° sp=-0.1f’W<0.02
The endoscopelens1:4 70° B(0k)+B(ak)+B(ak)
The analytical way to the definition of the correction possibilities on the example of the symmetric eyepiece
The Seidel sums of the symmetric eyepiece
Thus it is possible to judge about its correction possibility without the definition of the dimensional features of the eyepiece.
The synthesis of the wide-angle eyepiece with corrected distortion
In total the research forms the base for following development of the OSRP in general and designing of the different units in particular
