Special Issue Information

Dear Colleagues,

Lasers have long been used as highly sensitive measuring devices. With the rise of laser equipment, the applications of laser equipment are becoming more and more extensive. For example, laser sensors measure the position, displacement, speed, and vibration of objects. Laser sensors include different types: laser distance sensors, laser displacement sensors, laser light curtain sensors, lasers for investigating the optical properties of media, laser Raman sensors, random laser sensors, etc. With the maturity of laser sensor technology, this has led to widespread use of laser sensors in many areas. In addition to manufacturing, it can also be used in robotics, autonomous driving and biomedicine.

The goal of this Special Issue is to provide the most recent research results in laser sensor technology and its application. Topics include laser sensor design and new laser sensor technology, as well as the theoretical and numerical methods to retrieve information from laser-based sensors, application of laser sensors in various fields, and different types of laser-sensor-based devices and their applications.

The majority of current methods for measuring the angular deflection of a laser beam enable measurement only in one selected plane. However, there are tasks in which measurements of laser beam deflections in 3D are required. In this paper, we present a way of enabling two-axial measurements of the deflection of a beam based on a single-axis sensor. The key idea is to direct a laser beam, alternately, into one of two arms of a measurement system. In the first arm, the beam is transmitted directly to the angular sensor, while in the second, the beam is directed to the sensor via a special optical element that rotates the plane of the beam deflection; in other words, this element changes the deflection in the horizontal plane into a deflection in the vertical plane, and vice versa. To alternate the path of the beam, a variable phase retarder and a polarising beamsplitter are used. The proposed technique was experimentally verified, and the results confirm its effectiveness.
