A method, system, apparatus, and computer-readable medium for operating a laser attraction. Aspects include instructing a plurality of laser transmitters to each emit a laser beam, each of the emitted laser beams being detected by a particular receiver device. In addition, a signal may be received that indicates that one of the laser beams has been broken. In an aspect, the signal may be received from a receiver device that is associated with the broken laser beam. Further, the receiver device may be instructed to illuminate a light source when the laser beam is broken, the light source being part of the receiver device.

A sensor for a laser may contain an at least partially transparent plastic with a fluorescent material that receives laser light at one frequency and creates light inside the transparent plastic with a second, different frequency. The light at the second frequency may travel through the plastic to an electronic sensor mounted against the transparent plastic. The sensor may be several feet in length or longer and still detect a single impinging Class I or Class II laser beam. In systems where the position of the laser may be known, a set of linear gain coefficients may be determined to calibrate the electronic sensor, as the signal strength of a received signal may decay with the distance from the electronic sensor to the location where the laser beam impinges the plastic element.

A two dimensional scanning laser system may automatically detect a laser, then align and calibrate itself to scan over the sensor area. The system may have a laser with a controller that may cause the laser to be directed over two dimensions, as well as a sensor apparatus. The laser may be controlled with a mirror system that may pivot in two directions, thus allowing the laser to be scanned over a two dimensional area. The sensor may be a point sensor, where the laser may be positioned in a constant direction, as well as a larger area sensor where the laser may be moved across the sensor area to detect objects in a two or three dimensional space. An alignment and calibration sequence may cause the laser to scan across its operational area and detect the location of one or more sensors.

Laser alignment and calibration system for scanning lasers

An automated entrance device includes a housing and a first and second panel operably coupled to the housing. The panels are positioned approximately at a 90&#xb0; angle to each other. The first panel and the second panel rotate together from a first position to a second position to allow entrance to a user. After allowing a user to enter, the panels reset to the first position ready to selectively allow entrance to additional users.

A laser controller may operate a laser at a high power level, such as Class 3R, Class 3B, or higher, but may have safety interlocks to limit exposure to a safe level and may, as a system, be classified as Class 1. The laser controller may control a laser that transmits a light beam to a sensor, and may operate the laser in a high power mode when the sensor senses the light beam. While a laser is transmitting and the laser beam is not sensed, the laser may be operated within Class 1 power levels. When the light beam is broken, the laser controller may turn off the laser or change the power level to a safe level such that a person would not be exposed to any more energy than a Class 1 level. The laser controller may use various mechanisms to set a detection threshold and may use an ambient light sensor to determine when detection may be impossible.
