The most common laser used in the house

While the red laser remain the most commonly utilisés in the houses, laser pointers blue and green are growing in popularityé. These color laser alternatives that have power levels more élevés and you can use them for tâches à long portée. green laser pointers work most effectively for the astronomy course, while the pointers red gèrent of many tâches day-to-day.

laser pointers à home need a range much shorter than those that are nénecessary for activités more intense. Uses à long portée nécessitent a few advancedés supplé.... For example, the laser pointer blue collimatent généusually more quickly than red lasers. This ensures a point focalisé à longer distances, which allows you to keep a greater distance from your target without the loss of précision.

The caméra would take a laser pen infrared? That would be très useful to use it on my projector à distance. Attack a red laser in normal c&taxes;te à c&taxes;te with an infrared laser. Of this fa&case;there, you have a movable cursor (red dot) on l'écran, so that you can see o&where; your purpose, and can press the infrared button to click or drag the mouse! Although the red laser appears à huis clos? If yes, you can cover the lens with a filter, anti-IR for emp&stop, expensive is this?

using a laser pointer with an IR LED attachée on c&taxes;té is a très bonne idée. you can visually track the red dot on l'écran, and then click on the IR LED for a left-click of the mouse. the advantage is that you can stand away from the wall and find out o&where; you éwere on the point of click and the laser is just a way to keep track of the position of the cursor. the only problème that I see with this idée (besides the fact that the lumière ir générée and leakage of the laser could interférer with a système of follow-up IR own) is that you would not be able to déplace between étalonnages.

once you have calibré the program of the white board, it locks in the mémoire o&where; are the limits extéthan this écran. Then, if you take two steps to the left, m&stop, me if you can always point the laser dot to any point on l'écran, the source de lumière IR will be é - dyed by these two étapes &to the left. this is to rotate your wrist to point the laser dot, it changes the angle of référence éestablished between the surface and the IR source. you can use this idée effective, but you must maintain a posture of strict. I would imagine that this would not really be worth the trouble of déto develop the technique.
