Industrial and Scientific Applications USB2.0 Cameras for Industrial and Scientific Applications May 2012

Outline CMOS Cameras CCD Cameras Line Cameras

Why Buffered Cameras? On-board memory used to temporarily store captured images. Key advantages - Multi-camera applications Short & repeatable external trigger delay Arbitrary ROI’s (with Nx and Ny multiples of 4)

Rolling Shutter vs Global Shutter

Rolling Shutter vs Global Shutter Rolling Shutter cameras may distort moving objects Global Shutter cameras don’t have the problem

Rolling Shutter vs Global Shutter Pixels are exposed roll by roll Usually has higher pixel count Good for stationary or slow-moving objects May distort image for moving objects All pixels are exposed simultaneously Good for moving objects No image distortion

Cameras with Built-in LED Drivers for Illumination Camera and LED drivers share the same PCB Ideal for camera applications requiring LED illumination 4 channels (e.g. R, G, B, and white) No external power supply needed 1W available for LED illumination Controlled through the same USB and the same GUI-based software SDK includes both camera and LED driver functions Saves money Saves space Saves time Saves trouble

Window-less USB2.0 CMOS Cameras Why Window-less? Better sensitivity @ IR, VIS and UV Optics or other components can get closer to the sensor No unwanted optical interference due to multiple reflection Mission-critical applications

Key Selling Points of Industrial Cameras Highly reliable and widely tested SDK Excellent synchronization capability (i.e. short and highly-repeatable external trigger delay) Support multi-camera applications DirectShow, TWAIN and Linux compatibility USB protocol for non-Windows systems Easy for system integration (e.g. with GPIOs, trigger in/out, etc.)
