Photometrics’ Evolve EMCCD camera – automatic, real-time imaging data standardisation Dr Deepak Sharma Photometrics
Photometrics’ Evolve EMCCD camera is engineered to report data in standardised units, photoelectrons, in real-time. With low-level programming access to the CCD pixel array,
the Evolve camera can immediately provide any machine vision application with standardised imaging data without any calibration budget, equipment or expertise. The Evolve was designed for sensitive applications, such as LED and photovoltaic cell inspection or spectral imaging of pharmaceuticals, in which calibration requires significant time, budget, specialised equipment and human resources. Standard cameras require continuous calibration, because of the way they amplify photoelectrons and report data, which varies between units – and as sensors age. Photoelectrons, produced directly by light incident to a camera’s sensor, are independent of the camera or user-selected settings and therefore enable direct, quantitative comparisons of generated data.

First robust and feasible gesture control using time-of-flight technology Jochen Penne PMD Technologies
PMD sensors from PMD Technologies enable the real-time measurement of depth maps and
grey-value images at lateral resolutions of up to 204 x 204 pixels according to the time-of-flight (ToF) principle. This technology provides new perspectives
for human-machine-interaction: since the depth map measurement is independent of texture, environmental lighting conditions or gloved hands, the segmentation, detection and analysis of human hands can be accomplished in a way superior to the capabilities of 2D image-based approaches. With the CamBoard, PMD Technologies provides a fully USB- powered, webcam-sized ToF camera with an excellent potential to be integrated into consumer products. It enables intuitive and natural hand-gesture based interactions with
computers, machines and mobile devices. PMD Technologies has set up a trial implementation of a robust hand-gesture interface providing mouse cursor positioning, clicking, and drag- and-drop interaction.

Single lens 3D-camera with extended depth of field for industrial inspection Dr Christian Perwass, Lennart Wietzke Raytrix
Raytrix has developed camera technology and software algorithms that, from a single snapshot, can computationally generate images with an extended depth of field, variations in camera viewpoint, stereo views of the scene, and an estimation of 3D scene depth. The technology is based on a micro lens
array (MLA) with a specific design developed by Raytrix, which is placed at a precise distance from the image sensor. The price that has to be paid for the additional features is a reduced effective resolution of, at most, one quarter of the sensor resolution, and a varying effective resolution over the depth of field. The highly parallel algorithms developed by Raytrix to perform the refocus calculations can generate a 1 Megapixel image in approximately 10 milliseconds. The cameras are available directly from Raytrix or from IDS starting at €1,000.

Telecentric zoom lens ML-Z07545HR Nina Berlin
Schott Lighting and Imaging
Moritex and Schott have introduced a telecentric HR 6x zoom lens for 5 megapixel sensor
cameras. The ML-Z07545HR lens makes it possible to explore the entire potential that 5 megapixel sensors offer. With its optical zoom (0.75x up to 4.5x) that can be operated either manually or electrically, this lens can be used in a variety of different ways. The iris diaphragm and focus can be adjusted with high precision. The compact, lightweight lens is equipped with a C-mount. This product series offers
