Area Illumination
Laser based area illumination
Osela’s beam shaping capabilities allow for 2D area illumination, projecting specific fields of view with high optical power density. Applications include inspection, area imaging, and time of flight sensors.
A time of flight (ToF) camera is a range image camera system that employs time-of-flight techniques to resolve distance between the camera and the subject for each point of the image, by measuring the round trip time of an artificial light signal provided by a laser or an LED. The TOFI can be used to improve the working range of current market solutions for time of flight sensing.
Classic LED based illumination for 2D applications has its limitations at long working distances. Due to the high divergence of LEDs the illumination brightness is sometimes not sufficient to create enough intensity on the camera for image processing applications.
For enhanced illumination of 2D areas, the TOFI laser (or a stack of TOFI lasers) can be used for long working distance applications. Originally designed for time of flight applications, the TOFI offers significant advantages in long-distance applications such as in the traffic surveillance.
