The difference is that red-dot sights have contained aiming reticles, whereas laser sights use an emitted laser beam that must fall onto a target. Red-dot sights are used mainly for more accurate ADS (aiming down sight) firing and laser sights allow for less-accurate, but made more so, shoulder-firing.
With a red dot, or reflex sight, you have a low power LED that produces the reticle, while a holographic sight uses a more powerful laser that bounces around to produce the holographic image of the reticle. The biggest impact of this difference is the duration of the battery life of the site. As the holographic sight consumes more power, it understandably dies quicker compared to a red dot sight. It is always recommended to turn off your site if you do not intend to use it for some time to avoid draining the battery. You can get any other idea about holographic from online as Olomagic.com.
To convert a dot laser to a line laser, you can use a cylindrical lens. This lens will focus the laser beam in one direction, creating a line instead of a dot. Simply attach the lens to the laser to achieve the desired effect.
The red dot sight from Call of Duty: Modern Warfare 2 was only available during the builds of MW3 and was never actually released for the game. For unknown reasons the red dot sight from MW2 was cut and they used a similar model from the original Modern Warfare but with changes. But an AK-47 with the MW2 red dot sight can be found in MW3 in the spec ops mission "Kill Switch".
When the dot product between two vectors is zero, it means that the vectors are perpendicular or orthogonal to each other.
The gradient of the dot product of two vectors is equal to the sum of the gradients of the individual vectors.
There is essentially no difference in the two, they both do the same thing but they look different on the outside. Technically speaking, a red-dot is a reflex sight.
an electric sight is a "red dot" sight that uses a laser to project a red dot where the airsoft bbs will go when you sight it it.

buy a laser point pen and duct tape it.
There are two types of laser sights for a gun. The first type is a scope which has a laser dot inlaid in the actual lens. This dot is brightened using a batter. The dot does not actually "cast on" to it's target. The second type of laser sight actually does cast on to the target, and will produce a visible dot even outside of scoping. These typically cost more than the scope type sights, and use more batteries. Overall, they are both around the same accuracy.
The holographic sight is a sight with a 1.5x zoom. The hybrid sight is a combination of both the red dot sight and holographic sight, you can switch between the two at any time. The hybrid sight is only in MW3. Related links have been added that describe the features of both sights
The difference is that red-dot sights are cheaper to make, less accurate, and not as durable as holographic sights are. Both use an LED (light-emitting diode) to create a reticle (target dot) imposed onto a clear surface, but holographic sights are usually more accurate at long distances and do not "change" position in the glass when looked through at a different angle, which the reticles of red-dot sights often do. The key to this difference is that red-dot sights refract the laser emitted by the LED only once, allowing room for error, whereas holographic sights refract the one beam from the LED multiple times from multiple angles so that each laser refraction will reach the same place every time and will appear to remain consistent in its position to the shooter's eye.

All good laser sights have 3 adjustments. Up/Down, Left/Right and lock. They are usually not knobs but allan wrench screws. Some Red-Dot sites have knobs. Laser and red-dot are two different kind of sites.
To convert a dot laser to a line laser, you can use a cylindrical lens. This lens will focus the laser beam in one direction, creating a line instead of a dot. Simply attach the lens to the laser to achieve the desired effect.
Buy what you want but here are some suggestions. the SMK 6x36 35mm dayscope, red dot laser aimer, bipod, susat sight, acog sight, red dot sight and finally if you have £15,000 to spend, a BW thermal scope.
The difference is the technology used in the printing. The dot matrix printer uses a matrix of needles that press through an inked ribbon to leave marks on the paper. The laser printer uses a roller system to leave charged area on the paper which attracts toner (fine particles of pigment) to stick to the paper. The dot matrix printer is largely obsolete nowadays; it has been replaced by laser/ink jet and thermal systems which are much quieter - making them more suitable for office and home use.
