Phase Measuring Deflectometry is a highly precise and full-field measurement technique
suitable for specular surfaces. Typically, computer displays are used to provide reference …

Phase-measuring deflectometry is an optical inspection technique for reflective surfaces. It
enables absolute, quantitative surface measurements, given a calibrated measurement …

Phase Measuring Deflectometry (PMD) is a non-coherent full-field measurement technique
based on geometrical optics, usually employed for specular surfaces. The measured phase …

Phase-measuring deflectometry is a full-field gradient technique that lends itself very well to
testing reflective optical surfaces. In the past, the industry's interest has been focussed …

In phase measuring deflectometry (PMD), the inspection accuracy of the defects and height
of the specular surface are related to the level of phase errors. The usage of numeric …

Featured Application The paper proposes a novel method of calibrating system parameters
for a PMD (phase measuring deflectometry) based system. This calibration method can be …

Phase Measuring Deflectometry (PMD) is a meanwhile established technique for optical
measurements of specular freeform surfaces [1, 2]. The basic principle is depicted in the left …

We present a new method to measure specular free-form surfaces within seconds. We call
the measuring principlePhase Measuring Deflectometry'(PMD). With a stereo based …

This paper presents a short review for phase measuring deflectometry (PMD). PMD is a
phase calculation based technique for three-dimensional (3D) measurement of specular …
