Exponential Correction Method on Shape from Focus for Improved Non-Uniform Illumination
Meng-He Chiu;Ju-Yi Lee

The purpose of this paper is to improve the non-uniform illuminated region by using exponential correction method. The experimental results show that non-uniform illumination often results in undesirable depth map. First we pre-process the image with exponential correction, then the depth map can be recovered by shape from focus (SFF).

Intensity Distribution Measurement of Free Form Surfaced LED Lamps by Projected Light Image Analysis Method
Wei-Lun Gao;Hsiao-Yi Lee;Hsin-Yi Ma

Through the projection light image analysis method, the light intensity distribution of a free form surfaced LED can be accomplished much faster than other approaches. Comparing the optical experimental results of the LED lamps by Gonio-photometer and the proposed projected light image analysis method,

Particle detection in different slice imaging using phase encoded common-path digital holographic microscopy
Yu-Chih Lin

This study presents a particle detection method by using novel phase encoded method in common-path DHM. The particles at different slice of the sample can be measured by using virtual spatial filter recording technique which can avoid the diffraction information from the other slice of the sample.

Study of PQ:PMMA film for grating recording using oxolane solvent
Te-Yuan Chung;Yung-cheng Cheng

PQ:PMMA can be dissolved in oxolane solvent and dispersed on glass substrate to form a film. Applying doctor-blade method with thickened solution, a rather uniform PQ:PMMA film can be formed. Series test on recording hologram grating on such film were performed and a corresponding model is established.

Error-controlled Pulse-encoded Patterns for Phase-shifting Projected Fringe Profilometry
Hao-Wei Sung;Chien-Ann Chen;Wei-Hung Su

An error-controlled method using pulsed-encoded patterns to identify fringe orders for phase-shifting projected fringe profilometry is presented. Phase-extraction and unwrapping can be performed directly by the pulsed-encoded patterns. There is no need to take additional projections for phase unwrapping.

A One-shot Method Using the 2D fringe-encoded pattern for Fourier Transform Profilometry
Huai-Syuan Huang;Zhi-Hsiang Liu;Wei-Hung Su

A one-shot method using the two-dimensional fringe-encoded pattern for Fourier transform profilometry is presented. The 2D fringe-encoded pattern provides additional information to identify the fringe order. Even though the surface color or reflectivity varies with positions, fringe orders can be identified precisely.

Estimation of the concentration of nonlinear refractive index inhomogenities by analysis of diffraction patterns obtained using TRIDH approach
A.V. Belashov;N.V. Petrov;Chau-Jern Cheng

The work is devoted to development of a new method for rapid estimation of the concentration of optical defects in the form of nonlinear refractive index inhomogeneities. The proposed method is based on analysis of the angular spectrum of diffraction patterns obtained using previously demonstrated TRIDH method.
