Piranha3 CMOS Line-Scan Camera
Dec 2010

WATERLOO, Ontario, Dec. 17, 2010 — Dalsa Corp. has introduced the Piranha3 CMOS line-scan camera. The high-speed model delivers 16-k resolution with a 3.5-µm pixel size and a 70-kHz line rate for ultrafast 1146-megapixel per second throughput. The high-speed interface achieves throughput beyond that of Camera Link.

With on-chip analog-to-digital conversion and correlated double sampling, the extended cable camera delivers low noise and a high dynamic range. It is suited for the inspection of large-area flat panel displays and printed circuit boards, along with document scanning and other high-throughput applications. It measures 150 × 80 × 77 mm.

To deliver its full bandwidth, it uses the new HSLink machine vision connectivity interface that takes the key strengths of Camera Link, adds new features and functions, and combines them with scalable bandwidth in 300-MB/s steps from 300 to 6000 MB/s, while using globally available off-the-shelf components.

The camera is supported by the proprietary Xcelera-HS PX8 frame grabber that delivers an image acquisition bandwidth of 1.8 GB/s and a host transfer bandwidth of 2 GB/s over multiple-lane PCI Express implementations.

All Piranha cameras are supported by the company's Sapera vision software. This core development platform includes more than 400 image processing primitive and industrial strength image analysis tools such as pattern finding, 1- and 2-D bar code and optical character recognition tools for part identification and detection, a color processing tool, separation and measurement applications, a blob analysis tool and an inspection metrology tool for real-world dimensional measurements.

Camera configuration parameters that are all software controllable, including flat field correction, exposure control, and gain and offset control.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
correlated double sampling
A technique for removing thermal noise and drift from focal plane assemblies by sampling the system output between views of scene elements and then subtracting the resulting value from the subsequent reading.
