Machine vision inspection using Lynx-512-CL provides you valuable information about process stability and quality assurance measurements.
Using area array (or 2-D) sensors for the imaging of fast moving objects or continuous webs can be a problem if the frame read time of the sensor takes too long.
In these situations the use of a line-scan sensor is an excellent solution. In contrast to area array sensors, line-scan sensors have a very fast line read time. Therefore they are perfectly suited to image high speed objects or webs. With a single line of pixels, line-scan cameras build continuous images not limited in their vertical resolution. The vertical resolution comes from the object’s own motion (for example on a conveyor belt). The image of, for example, a 1024 pixel line-scan sensor will be 1024 x N pixels, where N keeps growing as long as the camera is running.
Another advantage is the price of a line-scan sensor, which is much lower compared to a high resolution 2-D infrared sensor. This is especially of interest for infrared applications.
Line scan infrared imaging is used in a multitude of applications, based on infrared imaging or infrared spectroscopy.
Imaging applications with line scan SWIR cameras are:
Spectroscopy means that we use diffracted light and look at molecular vibrations bands (in the SWIR band, i.e., 800 to 1700 nm range) in order to identify a specific material. For spectroscopy, typically rectangular pixels are preferred as they enhance the sensitivity. Typical applications are Raman spectroscopy (with laser excitation at 1064 nm), or spectrometers for optical performance monitoring in dense wavelength division multiplexing (DWDM) networks, where different wavelengths (around 1550 nm) are multiplexed in one optical fiber.
We offer a range of SWIR line scan cameras called Lynx. The Lynx line scan cameras are very small SWIR line scan camera available in three line resolutions of 512, 1024 or 2048 pixels. The maximum line rate goes up to 40 kHz depending on the model. For an easy integration the Lynx SWIR line scan cameras feature an industry-standard interface such as CameraLink or GigE.
