A method for aligning a projected beam on a reflector in a reflective-type beam detector, the method including adjusting the projected beam so as to: project on to substantially all, if not all, of a reflective surface of the reflector; or project on to at least a portion of a reflective surface of the reflector until a constant, or within a predetermined threshold of a constant, signal is received from the reflector; and detecting one or more edges of the reflective surface of the reflector and thereby: centering the projected beam, so as to align an approximate center of the projected beam on, or within a predetermined threshold of, an approximate center of the reflective surface of the reflector; and/or determining a shape or profile of the reflector.
A method for aligning a projected beam on a reflector in a reflective-type beam detector, the method comprising:
A method for searching for and projecting a beam onto a reflector in a reflective-type beam detector where initial illumination of the reflector has been unsuccessful, the method comprising:
A beam detector apparatus, for aligning a projected beam on a reflector, the beam detector apparatus comprising:
A reflective-type beam detector apparatus for searching for and projecting a beam onto a reflector, the reflective-type beam detector apparatus being configured to project the beam to a first projected location in a vicinity of the reflector and, if no signal is detected from the reflector or a signal detected is less than an operable threshold, the reflective-type beam detector apparatus is configured to project the beam either constantly or intermittently while tracing at least part of a circumjacent pathway around the first projected location in order to detect a location of the reflector.
