Machine Vision Cameras

Sony, Park Ridge, NJ, offers the XCD series of machine vision cameras that use the high-bandwidth 1394b interface and are designed for applications ranging from parts inspection to microscopy. They are available in either monochrome or raw color versions. Each fit the same compact form factor to ease integration in industrial environments, and can be configured as a star connection or daisy-chained. Sony’s 1394b software driver maximizes the 800 Mbps bandwidth and can daisy-chain up to 62 cameras with an optional external power supply. The series comprises three sets of cameras offered in VGA, SXGA, and UXGA resolutions.

Digital Microscope Camera

The PAXcam2+ digital microscope camera from MIS, Villa Park, IL, has a CCD sensor with the ability to capture low-light images, and features an enhanced dynamic range for color rendition and tonal qualities in captured images. The camera addresses microscopy applications such as polarized light, darkfield, Nomarski DIC, and fluorescence applications. The camera includes extended camera exposure range, low-light sensitivity, and true-color display and capture. All PAX-cams have a continuous white balance function, external mount for use as a macro camera, and USB-2 connectivity. The camera is suitable for applications such as microelectronics, semiconductor, LCD display manufacturing, materials sciences, and life sciences applications.

Network Camera

Axis Communications, Chelmsford, MA, offers the AXIS P3301 network camera with multiple H.264 streams. The fixed-dome camera uses the company’s ARTPEC-3 chip and is designed for unobtrusive video surveillance in exposed indoor environments. It features progressive scan and a wide dynamic range, providing images of both illuminated and low-light areas. Multiple H.264 streams and Motion JPEG streams can be provided simultaneously in full frame rate, or individually optimized for different quality needs and bandwidth restrictions.

Widescreen Operator Panel

Beijer Electronics, Schaumburg, IL, has released the H-T70t operator panel, part of the H-series that offers fundamental HMI functionality for machines and processes. The H-series includes keypad and touchscreen panels with displays ranging from 3.0 to 10.4". The H-T70t widescreen panel offers 800 × 480-pixel resolution on a 7" display. The TFT-display ensures the information is presented with clarity and a high level of detail. The panel is available in two versions, one with a built-in Ethernet port. Both models have a touchscreen interface, a menu key, and six user-defined function keys. USB-support is provided with two host ports and one device port.

Large-Format MWIR Lens

StingRay Optics, Keene, NH, offers a 50-mm midwave infrared (MWIR) large-format lens assembly with an optional microscanning and step-stare sensor capability. The lens can be a standalone solution for large-format detectors or used in conjunction with enhanced-resolution features. The lens is used with cooled cameras with focal planes up to 28 mm diagonal. The speed of the lens is based on an F/2.3 cold shield arrangement, and the 50-mm focal length is derived from the required 1-meter sampling area at an operating distance of 2.5 km. The lens provides diffraction-limited performance over the entire field of view.

Quantum-Inspired Maximizer

A report discusses an algorithm for a new kind of dynamics based on a quantum-classical hybrid-quantum-inspired maximizer. The model is represented by a modified Madelung equation in which the quantum potential is replaced by different, specially chosen “computational” potential. As a result, the dynamics attains both quantum and classical properties: it preserves superposition and entanglement of random solutions, while allowing one to measure its state variables, using classical methods. Such optimal combination of characteristics is a perfect match for quantum-inspired computing. As an application, an algorithm for global maximum of an arbitrary integrable function is proposed. The idea of the proposed algorithm is very simple: based upon the Quantum-inspired Maximizer (QIM), introduce a positive function to be maximized as the probability density to which the solution is attracted. Then the larger value of this function will have the higher probability to appear.

Genetic Algorithm Optimizes Q-LAW Control Parameters

A document discusses a multi-objective, genetic algorithm designed to optimize Lyapunov feedback control law (Q-law) parameters in order to efficiently find Pareto- optimal solutions for low-thrust trajectories for electronic propulsion systems. These would be propellant-optimal solutions for a given flight time, or flight time optimal solutions for a given propellant requirement. The approximate solutions are used as good initial solutions for high-fidelity optimization tools. When the good initial solutions are used, the high-fidelity optimization tools quickly converge to a locally optimal solution near the initial solution.
