The laser grid
It’s been a few years since we began ghost hunting, but already the technology has taken a huge leap forward. There are many items out there that can give you higher quality ghost hunting experience and stronger evidence of paranormal activity. One of these new and innovative items is the laser grid.
In this video, you see a pair of paranormal anomalies traveling through a laser grid. This video was taken during a private investigation of a home in Louisville, KY. In the video, you see what appears to be two entities, one following the other.
How the laser grid works
Laser grids are used to detect entities that move in front of a stationary video camera. A laser grid works by distributing a laser through an optical glass lens. The lens scatters the laser beam into patterns of light including a grid of dots. The pattern of the laser grid can be adjusted by turning the cap. A tripod-mounted video camera can then be set to monitor and film any movement within the laser grid pattern. The laser grid is small and easy to carry to your next ghost hunt; it’s also easy to quickly set up. Just set up and ask the ghosts to disrupt the light or move across the area and cause the grid to move.
Since the camera isn’t moving (or the tripod on which it’s mounted), the only movement that can be recorded is of anything that moves across the stationary set of green laser dots, causing them to appear to have moved.
Laser Grids to detect shadow people
Laser grids can capture the presence and movement of ghosts or other visual disturbances during a ghost hunt investigation. This is especially helpful in cases where you may be dealing with shadow people. This is because the darkness of their form is much more likely to interrupt and be tracked by the light beams of the laser grid.
You’ve most likely seen the laser grid used on ghost hunting television shows. A recent episode of Ghost Hunters showed the laser grid being used to detect the presence of spiritual entities. The result? The recording of the laser grid revealed the distinct outline of a shadow person walking through the targeted area. The lights visibly bended as they landed on a dark and possibly semi-physical presence that passed through the grid. This is something a standard camera probably would not have been able to catch on it’s own!
Do’s and Don’ts for using a laser grid during your ghost hunt
- Do make sure everything is stable. The laser grid is designed to detect movement. For that reason, it’s important that it isn’t moving itself. You need to make sure that you are using a stable video camera and tripod that won’t wobble or move while being used or if a person is walking nearby. The slightest movement will corrupt your data since the dots will look like they have moved when they haven’t.
- Don’t cast the laser on movable objects. Since the laser grid is being used to track any movement of entities through the area, make sure to only cast the light on non-moving objects like walls or furniture. Do not let the light fall on curtains, flags, fabric or other items that could change their position due to air movement.
- Do keep the laser out of everyone’s eyes. According to the FDA, “The light energy from a laser pointer aimed into the eye can be more damaging than looking directly into the sun. In addition, the startling effect of a bright beam of light aimed at someone driving a car or operating other machinery can cause serious accidents.” For that reason, make sure to use a lower-powered laser (5mW), which has less potential to cause damage. Also, don’t let the laser shine into your eyes, into the eyes of other people or pets. This will ensure that you operate a safe ghost hunt.
- Do make sure to buy a laser grid with a clamp. It’s key that you buy a laser grid with a clamp. This will allow you to keep the laser’s “on button” off whenever needed..
