Automated inspection is a major machine vision application. Inspecting any type of product in a manufacturing, quality control or even biological specimens, in an automated fashion improves throughput and accuracy. Today’s image processing tools (hardware and software) enable highly repetitive inspections to be totally automated reducing costs. Historically, applications such as bottle and beverage inspections used these techniques. Now these are being implemented in medical and biological testing.


machine-vision-applicationsThe Imaging Solutions Group works with such applications and our new LightWise Allegro USB3 Camera Family is ideally suited to this work. The LW-AL-CMV4000-USB3-C camera uses a CMOSIS CMV4000 image sensor that has 5.5 micron pixels and has a high frame rate for speeding up the processing.

From Wikipedia = http://en.wikipedia.org/wiki/Assay
“An assay is an investigative (analytic) procedure in laboratory medicinepharmacologyenvironmental biologycontinuous delivery and molecular biology for qualitatively assessing or quantitatively measuring the presence or amount or the functional activity of a target entity (the analyte) which can be a drug or biochemical substance or a cell in an organism or organic sample.”

DNA Analysis & Cell Biology tests typically use assays that are small test vials.  Cameras are used to gather images of the vials and image processing algorithms can be used to analyze and deliver results of the tests.  For example, an assay vial can be filled with a biological sample and a reagent applied. Then when viewing the assay with a camera that is illuminated with a particular wavelength of light will fluoresce.  The resulting image will show infected cells as dots within the image. See below as an example.
