Ghost Detector

About Ghost Stepper


The all new micro-controlled Ghost Detector light works on a split and mix spectrum.
The unit works in conjunction with full spectrum camcorders. Available soon. 

The Idea of the ghost detector light, is that we don't see in the ultra violet range or near infrared, we can see in the visible spectrum of light which is a very small portion of bandwidth of the whole electromagnetic spectrum, infrared and ultra violet is just outside each end of our general range, however our cameras can see in parts of this spectrum.

Our most noticable colour is a greenish yellow colour, which peaks at around 555nm, and drops off quite rapidly for other colours. 

When you look at Most Haunted and programs like that there's always a green hue in the background, the reason for this is because if a shadow is cast against this light level, we are more likely to see it, Not meaning the night vision just the studio lighting etc. 
Same principle for safety jackets, and work coats etc, it is generally the most noticeable colour. 
The peak wavelength of the ultra violet led is around 395-405 nm, when looked at appears as a purple colour, and not that bright, this is the fall off frequency in our visible range, so at peak it is a lot brighter, we can see the effect when white fluoresces or other objects glow.
Paranormal investigators are interested in this Uv range as well as infrared, if entities are moving in this part of the spectrum Uv cameras may pick up and record. 
 

How it works, Using a micro-controller and transducer driver circuits to enable control of the powerful 2 x 3 watt Uv and Ir Leds, and 3 x 1 watt Red, Green and Blue Leds for more subtle lighting. Each of The 3 watt Leds are approximately equivalent to 30 standard leds, and each of the 1 watt leds around about 10 leds
in this order UV, B, G, R, IR, which is under your control, by means of stepping through 32 possible binary combinations. The order sequence is ultra violet through to infrared with RGB in the middle, 32 possibilities. example you can record in Uv and green, UV and IR, or blue and red, RGB and UV, or any other combination. Just simply step through them and leave on preferred lighting condition, or test and see which suits best. The other programs inbuilt are, the Spectre Strobe, this feature strobes between IR and UV, which gives a strobe effect, at them light levels. 
As a strobe can have the visual affect of slowing down the apparent motion of things
this would seem like a favourable mode to record in.

Among the strobe modes are Uv strobes with 3 settings of 5Hz, 25Hz, and a 6.6 Hz, therefore the periodic times are 200ms, 40ms, and 150 millisecond intervals.
The frequency 6.6Hz Has the mark space ratio changed, whereas it is off for 100ms and on for 50ms, this gives it a more uneven type of pulse/second.
The infrared strobe modes are the same.
A joint infrared and Uv strobe is another function, these strobe together, and also toggle at a given rate.
Moving from the strobe functions there is an infrared constant light, and a burst of Red Green Blue at certain intervals.
 
Another function is an automatic 'count up the bandwidth in binary', this allows all combinations automatically to step up the bandwidth and then repeat, apart from the strobe modes and single step modes. Each light condition is present for 5 seconds, the full sequence is nearly 2 minutes, then it repeats, in this mode.
See if a ghost steps in to your light!
