This paper provides a set of polarization aberration fields that are useful for understanding polarization aberrations in optical imaging systems. The aberration function of a plane symmetric system is used to build the polarization fields. Polarization aberration coefficients for a system of spherical surfaces are also given.

We apply a digital camera with two prism arrays to capture a stereo image of the corrected chromatic aberration and distortion. The doublet prisms are used to correct chromatic aberration. The camera distortion with two prism arrays can be increased, and reduced by the lens optimization.

In this research, an optical integrated module including a liquid-filled lens, a flexible sensor membrane and a self-adjusted optical compensation component was designed. We studied the optical relationship (which is called compensation function) between the liquid-filled lens and the sensor membrane to make the system has good optical characters. According to compensation function, this module compensates the optical character between lens and sensor membrane to obtain a clear image by adjusting the internal pressure and volume of the liquid in the liquid filled optical system. For a single lensoptical system, the curvy sensor membrane has better performance than flat type sensor in off optical axis due to Petzval surface is curved. An optical experiment was set up to measure the performance of the module to prove the idea, and the results show that the module achieves the desired effect.

We provide analytic formulas for fews aspheric terms either plano-convex or convex-plano aspheric lenses. These formulas are obtained considering an expansion in Taylor's series from exact caustic equation produced by aspheric lenses. A comparison between our method and numerical methods of design are presented, showing a well agreement in order to reduce the spherical aberration.

This paper proposes a new zoom lensdesign with intermediate image. The two 3x zoom lenses are independently designed and then cascaded to a 9x zoom lens. The concept of intermediate optics is applied in this paper in order to minimize size of front diameter and overall length. The final layout shows the proposed 9x zoom lens can effectively miniature the front diameter of lens about 44.25%.

This article deals with automatic power balancing along an optical line. For optimal transmission of an optical signal it is important to achieve certain parameters such as the signal to noise ratio orchromatic dispersion and also the sufficient output power level of in-line amplifiers. Pump diodes in amplifiers suffer from aging of material and therefore the driving current of pump diodes has to be accordingly increased to achieve the same gain as in the moment when the pump diodes were new. The use of a minimal required driving current leads to the longer lifetime of optical pumps. Therefore an automatic power balance is one of the methods used to achieve these goals.

A compact encapsulating lens is proposed and analyzed, which simultaneously collimates and mixes the tunable light from red, green and blue (RGB) light-emitting diode (LED) chips. Colored LED chips are embedded within a spherical lens, and a section of the sphere that surrounds chips is mirrored with a diffuse reflector. Color light is mixed by multiple total internal reflections (TIRs), the scattering mirror breaks TIR, and light escapes only in a narrow beam in the forward direction. The color distribution, the beam pattern, and efficiency are analyzed by Monte Carlo ray tracing calculations.
