An access protection system comprises a first safety sensor, a second safety sensor, and an electronic control device that is in signal connection with the first and second safety sensors. The first and second safety sensors are laser scanners that each form a safety protected field and that each form a first detection protected field in operation and that are arranged such that the first detection protected fields do not overlap at least regionally. The electronic control device is configured to trigger a safety function on a penetration of an object into the safety protected field of the first and/or second safety sensors and to change the operating state of the access protection system when a penetration of the object is determined both into the first detection protected field of the first safety sensor and into the first detection protected field of the second safety sensor.

An optical seismic surveying system including, a multibeam laser source including a plurality of laser-sources, a Diffractive-Optical-Element (DOE), an imager and a processor. The laser-sources direct respective laser-beams toward a single common focal point. The DOE is located at a single common focal point and configured to split each laser-beam into a plurality of laser-beams, toward an instantaneous area of interest.
