Camera Trends 2012: Speed, Resolution, and Software

Cameras are still an important technology feature in manufacturing and inspection applications, but they are also increasingly valuable in non-traditional sectors. As part of June’s OEM Camera Directory & Guide, we look at three factors driving imaging tools: speed, resolution, and software.

Generating Electricity From Viruses?

Berkeley Lab scientists have developed a way to generate power using harmless viruses that convert mechanical energy into electricity. Their generator is the first to produce electricity by harnessing the piezoelectric properties of a biological material.

Light Source Enables Endoscope Miniaturization

This work will explore an illumination system's potential to miniaturize traditional endoscopes by shrinking the size of the channel used to deliver light. Physical space constraints continue to impact advanced procedures such as single-incision laparoscopic surgery, robotic-assisted surgery, and other minimally invasive surgical procedures. Additional functionality and instruments are being squeezed through the smallest incisions possible. Available space continues to tighten with the migration of larger diameter, three-dimensional, high-definition endoscopic imaging systems into minimally invasive procedures. Fortunately, a significant portion of the endoscope, the light delivery channel, can be reduced in size, thereby allowing the space to be used for other purposes, or for shrinking the endoscope itself.1

Real 3D Visualization: The Promise of Virtual Holography

The Heart of Virtual Holography There are a number of drawbacks to traditional two-dimensional environments. In 2D, images appear flat and only offer one perspective. In 3D, images have depth and offer multiple perspectives. A true virtual-holographic representation overcomes the limitations of even the very highest resolution 2D flat screen display. Part of the benefit of a 3D environment is the comfort of the experience; as in the real world, there are no conflicting cues and no need to envision how a 2D projection will appear in three dimensions — with 3D, you see it and operate with it exactly as it is.

Benchtop Imaging Devices: Making Fluorescence Microscopy More Accessible

Auto-fluorescent proteins have become an indispensible tool for cell biology research over the past decade. Originating from sea creatures such as jellyfish and sea anemone, these fluorescent proteins come in a rainbow of colors and are used to monitor cellular processes like protein localization, receptor signaling, and protein trafficking.

Software Toolkit Inspects Automotive Components

MPC , a Walworth, Wisconsin-based manufacturer of plastic parts for the automotive industry, builds many types of components. One such product is the oil filler cap for the car’s engine. The cap is made of injection-molded plastic, with a rubber O-ring seal around it, and a pad-printed logo and instructions at the top (Figure 1). To ensure design consistency, the caps must go through an inspection process. The goals for the component inspection include:

Split Camera

Industrial Sensor Vision International (ISVI) Corp. (Cheshire, CT) has introduced two split cameras for automation, PCB, and wafer inspection. The 5 Mega Pixel / 30 FPS Split camera has a 1.67 x 1.67 μm pixel size; CMOS sensor size of .22"; Camera Link functionality, and global shutter. The device features 8 bits per pixel and a .31V/lux.s sensitivity. The 10 Mega Pixel / 15 FPS Split camera has similar specifications, along with a CMOS sensor size of 0.434". Both cameras are available with cable length of 200 mm or 500 mm. The cameras use M14 mount type and have optional 13.4μm / 18.2μm lenses.

Contrast Sensors

Pepperl+Fuchs (Twinsburg, OH) has announced DK12-11-IO Series Contrast Sensors. The DK12-11-IO sensors use a three-color light source to detect differences in two colors of media. The components are IO-Link-compatible, enabling them to provide enhanced configuration options and visibility of the sensor’s color evaluation. Additionally, the sensors include Pepperl+Fuchs’ 4- in-1™ output, which delivers four output options from a single sensor.

Programmable Camera

Linux-based, programmable cameras from VRmagic (Cambridge, MA) are now available with miniature connectors. For its Linux-based intelligent cameras, VRmagic offers a back end with Picoblade™ connectors for Ethernet, USB 2.0 Host, RS232, and General Purpose I/O Analog Video Output. Additionally, a PCB with DVI or HDMI output can be connected to the cameras. The external board is connected with the PCB stack via a flexible printed circuit cable (FPC). Synchronized image recording and display is also possible via DVI or HDMI up to 60 Hz.
