A laser scanner () including a housing () having a window (), a light source () for emitting a light beam (), the window () being transparent to the wavelength(s) of the light beam (), a scanning mirror () rotatable about an axis of rotation (X) for deflection of the light beam () toward a scanning area (SC) so that the light beam () periodically sweeps at least one sweep surface, and for deflection of return light from objects or persons in the scanning area (SC) into a light collection path, a motor () for rotating the scanning mirror (), a photodetector element () for generating an electric signal, arranged in said light collection path, wherein the motor (), the light source (), and the photodetector element () are all housed within the housing () on a same side with respect to said at least one sweep surface.

Laser scanner

A coaxial photoelectric sensor may include both an optical emitter and optical receiver disposed on a printed circuit board. A total internal reflection optical component may be optically aligned with the optical emitter so as to reflect an illumination signal generated by the emitter. A reflective optical component may be optically aligned with the total internal reflection optical component so as reflect the illumination signal received from the total internal reflection optical component. A target reflector component may be optically aligned with the reflective optical component to coaxially reflect the illumination signal received from the reflective optical component. An optical detector may be configured to generate an electrical signal in response to receiving the illumination signal.

Photoelectric sensor with coaxial emission and receiving optical paths

A laser scanner which includes a transmission subsystem and a reception subsystem. The transmission subsystem includes a light source which emits a light beam and a scanning mirror rotatable about an axis which reflects the light beam toward a scanning area and which directs return light from objects toward the reception subsystem. The reception system may include a collecting mirror dimensioned and positioned to receive the return light from the scanning mirror. The reception system may also include a dichroic or interference filter disposed between the collecting mirror and the scanning mirror. The interference filter filters the return light from the scanning mirror and provides the filtered return light to the collecting mirror. The reception subsystem also includes a light detector disposed between the interference filter and the collecting mirror, in operation the light detector receives the filtered return light reflected from the collecting mirror.

Laser scanner and optical system

A laser scanner which includes a light source which emits a light beam and a scanning mirror rotatable about an axis which reflects the light beam through a tilted protective window toward a scanning area and which directs return light from objects toward receiving optics. The laser scanner may include a collecting mirror which receives the return light, and an interference filter disposed between the collecting mirror and the scanning mirror. The window may include an anti-reflective coating which reduces reflection of internally scattered light. The tilted window may direct the reflective component of internally scattered light into a zone where an energy light absorber is present. A bulkhead system which may include a separation baffle may be provided to prevent light incident on the interference filter at an angle which is below an acceptance angle of the interference filter.

In an apparatus and a method for acquiring and reading optical codes, the indication of the reading result is carried out projecting a luminous figure onto the optical code, that is to say in the position on which the attention of the operator is focused. The luminous figure can have an information content also more complex than the simple indication of the end of the reading.
