We develop a novel light bar waveguide design to produce a glareless light-emitting diode (LED) lighting tube. We design optimal parameters, such as the gap y between the tube and the reflective surface, the relative distance x between the lens and t

In this paper we present an efficient two-stage method combining the merits of the Taguchi method and neural network software to achieve nonlinear fine optimal lens grinding parameters for both the roughness and the curvature deviation robust over a

IR optical systems such as Petzval doublet refractive lenses or Cassegrain reflective mirrors are either expensive or poor in image quality. Taking advantage of the low cost of reflective mirrors, here we present an optical design of Double Cassegrai

Making use of the idea of synthetic discriminant functions (SDF), a simple way to synthesize a shift, rotation and limited size correlation filter is proposed. The SDF is synthesized by superimposing four 2nd order circular harmonics of a training re

The digital music editor software "Cool Edit Pro 2.0" is used to design a virtual hearing testing system. This system has following advantages. First, its signal frequency can be set at will. Second, its dynamic range of signal intensity can reach up

The system consists of two mutually orthogonal linearly polarized laser beams carrying the Fourier spectra of a reference pattern and an input pattern into a photorefractive crystal, respectively. The image of every reference pattern in the input wou

A scheme capable of demonstrating shift- and rotational-invariant associative memory is presented. The scheme can be implemented both digitally and optically. In optical implementation, we use one holographic spatial frequency filter and one ordinary

A simple way to synthesize a shift, fully rotational and limited size invariant composite matched spatial filter for a coherent optical correlator is proposed. We use circular harmonic components of the same order of a reference pattern in different
