This paper describes the features of the formation of measurement signals in a polarimetric ac magnetooptical sensor with a twist-type lightguide and algorithms for processing them. The results of modelling the sensor's reaction to the variation of the parameters of the sensitive loop are presented. The calculational characteristics are compared with the parameters of prototypes of the sensor. © 2010 Optical Society of America.

Objectives with numerical apertures of 0.1-0.4 have been developed and fabricated for focusing laser radiation. A feature of the objectives is that they use an aspheric surface of the same form regardless of the numerical aperture, while the objectives are capable of obtaining a diffraction-limited focusing spot at various wavelengths. © 2010 Optical Society of America.

This paper discusses how birefringence in the elements of the optical channel affects the result of the computation of the relative rotation of objects when a polarization method is used to determine the angle. A method of dual-spectral probing of the optical channel is proposed and experimentally checked that makes it possible to automatically determine the optimum relative rotation of the elements to minimize the influence of birefringence. © 2010 Optical Society of America.

This paper presents an algorithm for constructing the convex envelope of an object, based on an analysis of the derivative of the chain code of its boundary. The construction process consists of selecting boundary points with a positive derivative that satisfy a proposed convexity condition. Such points determine the vertices of a closed polygon that is the convex envelope of the object. A method is proposed for estimating the number of holes and the convexity coefficient, based on the ratio of the perimeters of the object and of its convex envelope. © 2010 Optical Society of America.

This paper discusses the features of the transformation of the polarization state of light when it propagates along a spun-type lightguide. The compensation setup of a polarimetric current transducer with a double pass of the sensitive loop is described. Based on the modelling results, a formula is derived for the dependence of the transducer sensitivity on the polarization characteristics of the lightguide and the size of the measurement loop. Results are presented from a measurement of the relative sensitivity of a prototype of the transducer. © 2010 Optical Society of America.

It is shown that the use of basic lenses with aspheric surfaces makes it possible to create various types of optical systems. Designs are proposed for ophthalmic objectives based on the use of basic aspheric lenses with compensated spherical and field aberrations. Ophthalmic objectives have been developed with two aspheric high-refraction correction surfaces with refraction from 80 to 116 diopters and a field of view 2ω from 90° to 118°. © 2012 Optical Society of America.

It is shown that optical elements have an increased radiance factor in the UV region. The objects that form the background on which the detection is carried out absorb UV radiation in this case. This suggests that the UV region is promising for detecting optical devices because of the increased contrast. © 2012 Optical Society of America.

This paper discusses the characteristics of laser radiation reflected from a catadioptric retroreflector as a function of the field-of-view angle in the presence of deviations of its geometrical parameters-variation of its length along the axis, variation of the radius of the reflecting surface, and decentering of the surfaces. The calculations use third-order aberration theory and the Fresnel-Kirchhoff integral in the Fraunhofer approximation. © 2011 Optical Society of America.

This paper proposes a new design for a retroreflector consisting of a biconvex lens with concentric surfaces, the back one having a mirror surface. Based on a calculation of the third-order aberrations and diffraction, calculated by means of the Fresnel-Kirchhoff integral in the Fraunhofer approximation, the influence of the length of the retroreflector on the axial luminous intensity is investigated. © 2011 Optical Society of America.
