"The video and pictures shows Time Resolved (TR) PIV results of mechanical properties of the body of a fish. The study was done to explore the source of high efficiency during fish swimming. Researchers investigated the viscoelastic properties of the fins, muscle and skin of Crucian carp (Carassius Auratus). Comparison of these results with the cruising frequency of Crucian carp shows that the dissipation due to internal viscoelasticity during cruising is small. Microvec PIV system was used for this research with a 1.5W CW semiconductor laser, Imperx 640 x 480 pixel camera with Epix frame grabber recoding at 170 frames per second."

"The images show PIV and LIF results in 200μm wide micro channel. First experiment showing flow characteristics in two single-phase mixing. Second shows two phase flow characteristics of oil-water mixed measurement. Laser used for the experiment was double pulse 532 nm Nd:YAG solid-state pulsed laser, 350 mj × 2; 15hz with pulse width of 6-8 ns. 5 megapizel camera with the maximum sampling rate of 15Hz using double exposure mode with Epix EB1 frame grabber and MicroPulse725 V5 synchronizer. Maximum speed of the plane was 1m/s and the special resolution was 0.475 um / pixel. Latest MicroVec 3.5 software was used for the calculations. "

"We used an Epix Silicon Video 642 CCD camera attached to a trinocular inverted microscope with an adapter for imaging a large protein-coated region while maintaining a high resolution that contains enough detail to allow tracking of cells over time."

"Each series of images was imported into XCAP v3.2 software (Epix, Inc., Buffalo Grove, IL). XCAP software permits tracking of each cell in successive images."

System Arrangement Diagram Thomas D. Perroud and co-authors have extended the principle of optical tweezers as a noninvasive technique to actively sort hydrodynamically focused cells based on their fluorescence signal in a microfluidic device. This micro fluorescence-activated cell sorter uses an infrared laser to laterally deflect cells into a collection channel. The movie taken at 400 fps by a monochrome 1000 fps CCD camera (UF-1000CL; Uniq Vision) and saved at 10 fps by a PIXCI CL1-UF-1000-CL Camera Link Frame Grabber (Epix) shows the optical deflection of a cell (velocity ~ 20 mm/s) into a different microfluidic channel.

System Arrangement Diagram "In this example, the object was to record the detailed behavior of a combustion event—a fire or explosion—in a large field. Figure 1 shows the arrangement of the major elements of the vision system supplied by EPIX of Buffalo Grove, IL. The company designed and built the system based on three Basler A504kc Color Cameras and three PIXCI CL3SD Frame Grabbers."

In operation, reflected images from the vials are transmitted through the folded-optic assembly and imaged by a 1300 × 1030-pixel Camera Link M4+ camera from JAI Pulnix. Interfaced to a PC-based PIXCI CL2 64-bit/66-MHz PCI frame grabber from Epix, images are directly transferred to the host PC memory for image processing. “The motion control of the system needed to be tightly integrated with the imaging system,” says Budd.

B. H. McCormick, (2002) Knife-edge scanning microscope (KESM) - "Digital video from the multi-tapped linear CCD array of the CT-F3 camera is delivered via 8 channels at 25MB/s each to a Dell PowerEdge 2550 server. Camera interface cards (two for the Dalsa CT-F3-4096 line scan camera; one for the Dalsa CL-T5-2048 color line scan camera) provided by Epix, Inc. store this data in the dual processor."

John J. McCarthy Observatory "The EPIX frame grabber and software will be initially used in a demonstration of the effects of atmospheric turbulence on the image quality of stars. No doubt it will find many other uses over the years. One of the important aspects of encouraging high school students to explore scientific endeavors is giving them the sense that they are doing something new and unique. The EPIX donation goes a long way in that effort. We will be sure to keep EPIX informed about our progress."

Visual Servoing Setup "We are using a pair of high-speed digital cameras from DALSA, and frame-grabbers from EPIX, and rack-mount PCs running LynxOS. After I wrote the device driver for the board for LynxOS, a colleague, Gabriel Lopes, wrote for us a simple vision system which uses the Kullback measure to dynamically compute a threshold with which to segment an image. Currently his system can track a features position and orientation in real-time at 100 frames per second on a modest PII400MHz, with a window size of 128x128 (it may go faster, but this is as fast as we've tried -- the cameras can do 255Hz)."

"Design Solution:
A monochrome Panasonic RS170 camera was used to detect simulated potholes. The
data from the camera is passed into an Imaging Board from EPIX Inc. The formatted data from the EPIX Imaging Board is then processed to detect the presence of a simulated pothole and the centroid location of the pothole, in case one is present.

First, a threshold operation is performed on the image to obtain a binary image. Then, the noise from the environment is removed by analyzing the blobs in the image. The noise removed image is then processed with a circular regression procedure.

The XCOBJ/PXIPL Image Processing libraries16 provided by EPIX were used extensively for developing the control software." (19 February 2006)

Granular Materials Laboratory - "High-speed photography: A high-speed, long-acquisition digital camera system designed and implemented by Prof. Shattuck. It features 955 frame per second, 256 pixels array camera system based on DALSA CA-D6-0256W camera and Epix PIXCI D32 data acquisition board. In combination with an Adeptec 39160 SCSI disk array controller and six 18GB 10K rpm IBM deskstar hard drives (at 160MB/s sustained transfer rate), the system is capable of full frame rate acquisition for up to 20 minutes or one million frames with no data loss. This gives six orders of magnitude of temporal dynamic range.

By storing to hard disk array it can achieve 108GB at 160MB/s and can be upgraded if needed to 570GB at 200MB/s. Typically, commercial systems have limited acquisition times due to frame capture to RAM. Since the system is constructed using standard components, custom software had to be developed to take proper advantage of the system." (17 August 2007)
