We present an experimental configuration that enables form measurement from a single-shot camera exposure. It combines two-wavelength contouring with spatial multiplexing synthetic-aperture digital holography. The synthetic-aperture in this work is f

In the context of the segmented primary mirror of the E-ELT, the ability to measure the phasing state of neighbouring segments during day-time represents a way to mitigate the risk of potentially time consuming on-sky phasing after segment replacemen

We present an experimental configuration that enables form measurement from a single-shot camera exposure. It combines two-wavelength contouring with spatial multiplexing digital holography. This is achieved by simultaneously illuminating the test ob

Industry frequently demands fast and robust measurement techniques for the inline inspection of the full shape of objects in the micro range. We present a method for complete 360 degree measurement of the shape of a micro cup using digital holographi

Non-destructive testing (NDT) describes a wide range of methods for measuring and comparing physical quantities against a nominal condition. In this paper we describe and compare different optical NdT (ONDT)-methods with respect to their characterist

We present a shear interferometer that is based on an air wedge placed in the Fourier domain of a 4f-configuration as the shearing element. The two images are formed by the reflections from the front and reverse surfaces of the wedge. Due to a latera

In this paper we describe a highly miniaturized sensor head based on digital holography for endoscopic measurements. The system was developed to measure the shape and the 3D-deformation of objects which are located at places that cannot be accessed b

Using the image-based optical measurement method known as axially distributed sensing (ADS), the depth information of a scene is retrieved by evaluating images recorded with a camera positioned on multiple points along a common optical axis. We descr
