	Laser guidance - Wikipedia, the free encyclopedia
		Laser guidance is a technique of guiding a missile or other projectile or vehicle to a target by means of a laser beam.
		With this technique, a laser is kept pointed at the target and the laser radiation bounces off the target and is scattered in all directions.
		When it is close enough that some of the reflected laser energy from the target reaches it, a laser seeker notices which direction this energy is coming from and aims the projectile towards the source.

	Laser-guided bomb - Wikipedia, the free encyclopedia
		The reflected laser light ("sparkle") from the target is then detected by the seeker head of the weapon, which sends signals to the weapon's control surfaces to guide it toward the designated point.
		The earliest laser guidance seekers measured the intensity of the reflected laser light at four corners of the seeker window.
		To insure accurate guidance, the target must be illuminated for several seconds before launch, allowing the weapon's seeker to obtain a positive lock, and the target must remain illuminated during much of the weapon's transit time.

	Laser Guidance
		The laser sensor is mounted in a gimballed, aerodynamically aligned (ring airfoil - it aligns the sensor assembly with the weapon's velocity vector) assembly.
		Laser light reflected off a target passes through a protective nose window and an infrared filter and is focussed by an aspheric lens on to a four-quadrant silicon photoelectric sensor.
		Laser energy (designation) is fed into the optics by the use of a dichroic (reflective to particular wavelengths) combiner glass so that the laser beam exits the optics via the same path that external images enter the system.

		However, these tweezers are intrinsically limited by the diffraction of the laser beam to micrometer length scales, as strong lateral confinement requires tight beam focusing and a long effective length to transport the particles of thousands of Rayleigh lengths -- in other words a large figure-of-merit is required.

		If the laser comes on and will not go out, or will not come on without a hard jolt to the unit, the sensitivity needs to be adjusted.
		The laser light should be shooting just under the edge of the box thus being in-line with the tips of the forks.
		In order to align the laser, take the correct allen wrench (5/64) and screw the front "set screw" on the bottom of the unit directly under the laser in or out, depending on which way the beam needs to go until proper alignment is achieved.

	Semi-Active Laser (SAL) Precision Guidance System
		Except for line of sight verification and allocation of codes prior to the mission, the use of SAL does not impose further limitations or complexities when operating in good visibility conditions, (day or night) and therefore it is suitable for ad-hoc engagements of targets of opportunity and close air support.
		Modern laser guided weapons are integrating both GPS and laser guidance capability, offering high precision, all-weather attack capability.

		Any number of rockets may be linked to one laser, but only one volley of rockets may be guided at a time, and the laser must be able to hit the rockets' target.
		When a tuned laser and a modified rocket are fired together at the same target, roll normally to see if the laser hits the target and assess the laser's damage.

		Reasoning that advances in laser technology soon might make it possible to project the laser beam over sufficient distances to meet military requirements, they proposed using a laser as an illuminator, a means to mark the target by projecting a bright spot of light upon it.
		The original thinking had been that the laser must illuminate with continuous energy, roughly analogous to pointing a flashlight at a target, switching it one and holding the beam on the target until the missile hit.
		Specifically the command was asked to provide laser illuminators and operators, technical assistance and evaluation of the seeker proposals of the contractors selected by the Air Force to work on the bomb.

		The laser source can be the attacking aircraft, another aircraft, or troops on the ground - perhaps more than 10 miles (16km) away.
		The laser equipment, once "locked" onto the target, can remain pointing at it even if the target or the laser source moves.
		But the bomb needs to have the target "designated" - illuminated by the laser - all the time until it is about to hit, or it will lose its way.

	Laser Beam Guidance for Oshkosh Air Show - Aviation
		While AOPA does not believe that lasers pose a significant safety issue that warrants the use of temporary or permanent airspace restrictions, general aviation pilots should be aware that higher power lasers are more readily available, and at least one study shows that they may cause temporary vision changes from lasers.
		According to NORAD officials, the ground-based laser system uses safety-tested low-level beams of alternating green and red laser lights to alert pilots that they are flying without approval in designated airspace.
		According to the FAA, a preliminary test of the system showed that the laser illumination is "eye safe." However, the FAA contends, and AOPA agrees, that a number of important steps must be taken before the system is fielded.
