The Gabor superlens as an alternative wafer-level camera approach inspired by superposition compound eyes of nocturnal insects.

29 Aug 2009 We present the microoptical adaption of the natural superposition compound eye, which is termed "Gabor superlens". Enabled by state-of-the-art microoptics technology, this well known principle has been adapted for ultra-compact imaging systems for ... Read more...

Digital dental photography. Part 8: intra-oral set-ups.

20 Aug 2009 The majority of pictures taken in the dental surgery are intra-oral and this article looks at the practicalities involved in full-arch, quadrant occlusal, lingual (or palatal) and lateral views, as well as magnified images, oral mucosa, enamel ... Read more...

Determining the effect of species composition on temperature fields of tank flames using real-time holographic interferometry.

8 Aug 2009 Interference fringe fields and the visible flame field of a 50 mm diameter n-hexane tank flame were simultaneously measured using a real-time holographic interferometer with special image optics. An inhouse developed image processing method was ... Read more...
