Vision sensor adapts to LED lighting spectral balance
BOBST called on CSEM’s expertise to develop a CMOS vision system able to capture and simultaneously respond to movements at ultra-high speeds. The joint development was supported by the Commission for Technology and Innovation (CTI).
The key advantage of the vision system its ability to capture an accurate image of components that are moving extremely rapidly. The sysem contains a miniaturized optical sensor that is able to capture color images in a flash (800,000 lines per second), even in difficult environments. Such a sensor is adapted to the strong white LED lighting that is in widespread use in numerous industrial applications. The length of exposure can be programmed separately for each color to correct the spectral balance of the whiteness of the LED lighting and so improve read performance.
The device will be marketed by BOBST and is suitable for multiple applications, such as the monitoring of industrial processes at high speeds, high-performance color differentiation, surface inspection, and other industrial applications requiring high-speed optical inspection.
