German Light field specialist Raytrix has just added another use case of their range of plenoptic cameras for scientific and industrial use: The new Lightfield 3D Microscopy webpage page makes a first mention of the R5μ light field camera setup, which is optimized specifically for microscopy applications.
In the picture, Raytrix’ R5 high-speed video lightfield camera (model number R5-M-E-GE-A260-GS-A) is shown in conjunction with a Solino 0.8x High Resolution Tube for Fixed Magnification (177 mm, C-mount camera interface, Art.No. 045-200162), an objective adapter and a Leica objective lens for 10x magnification.
With their newest Youtube-Upload, German LightField specialist Raytrix demos the LightField features of their R29 camera.
The HD video includes original footage recorded with the high-end camera (resized from 3288 x 2192 = 7.2 megapixels; and 100 % crops), and demonstrates the reconstruction of 3D information – even at a subject-to-lens distance of 400 meters – as well as software refocus and extended depth of field.
Video frame rate for full-resolution imaging is 5 frames per second.
Not too long ago, the possibility to create LightField pictures with a mass-produced consumer camera sounded like dreams of the future. This was only the first step, though, and we’re looking forward to other popular imaging techniques (e.g. HDR and panorama imaging) to be augmented by LightField technology.
In a publication from 2012, computer scientists Clemens Birklbauer and Oliver Bimber from Johannes Kepler University in Linz, Austria presented a first approach towards creating Panorama LightField Images.
Graphics processor- and chipset manufacturer Nvidia regularly hosts an in-house conference titled “GPU Technology Conference” (GTC). The event is primarily targeted at engineers, scientists and journalists. At GTC 2012 Earlier this year, Raytrix co-founder Christian Perwass introduced the company’s LightField cameras, their fields of application and the technology behind the LightField:
In a news release that has somehow escaped our notice, German LightField specialist Raytrix announced an exclusive live demonstration at Photokina Preview 2012.
The report notes that Dr. Lennart Wietzke (Raytrix co-founder and CEO) and his team presented “the current version of the LightField camera”, and showed off live 3D LightField data processing, as well as software refocus. Continue reading
