A simple wavefront evaluation method is proposed which employs only one Fourier transform lens, one CCD camera and a digital signal processing procedure. The optical setup is sufficiently simple to be used in numerous types of optical systems. The fe

We propose a high-speed and parallel method to determine lens aberrations from its confocal axial response. This method analyzes the intensity confocal response including the aberration information of the objective lens by means of neural network alg

A non-axial-scanning confocal microscope employing a monochromatic light source has been developed. The system controls the defocus of an objective into three to .ve optimized states by using a membrane-adaptive mirror, and determines the axial heigh

Chromatic confocal microscopy has the advantage of short measurement times because of its parallel depth scan. As most white-light sources have limited optical output power, light-efficient setups are necessary. Using an extended detection pinhole is

Optical Metrology in Production Engineering.
Depth-scanning is an established technique in macroscopic and microscopic 3-D metrology. Representative in this context are the confocal technique and the white-light interferometry. A new fast depth-scanning technique has been applied to a confocal

CLEO/Pacific Rim 2003. The 5th Pacific Rim Conference on Lasers and Electro-Optics (IEEE Cat. No.03TH8671).
A non-axial-scanning confocal microscope by membrane mirror shape switching has been developed. The system controls the defocus of an objective by membrane mirror, and determines the height of an object from the confocal output value of each defocus.

Three-Dimensional Image Capture and Applications
The chromatic confocal approach enables the parallelization of the complete depth-scan of confocal topography measurements. Therefore, mechanical movement can be reduced or completely avoided and the measurement times shortened. Chromatic confocal po
