Abstract
A visual impairment device includes a power supply, an intense light source having two or more beams of intense light with different peak wavelengths and a wavelength bandwidth less than 50 nm, a modulator and a control circuit. The modulator operates to modulates the two or more beams of intense light to produce a spatial array such that at least one of the beams used to produce the spatial array has the requisite irradiance to cause visual impairment. In some examples, the beams of intense light are laser beams. Also included are methods of using the device to cause visual impairment of an intruder who enters a visual impairment zone created by said device.
Claims21
A visual impairment device comprising:
- a power supply,
- an intense light source connected to said power supply, said light source comprising two or more beams of intense light having different peak wavelengths and a wavelength bandwidth less than 50 nm,
- a modulator for modulating the two or more beams of intense light to produce a spatial array such that at least one of the beams used to produce the spatial array has the requisite irradiance to cause visual impairment,
- wherein the spatial array covers an area with a pattern of light beams made by (a) splitting one or more said beams of intense light into a plurality of beams to produce a pattern of discrete beams separated by a preselected distance, or (b) moving one or more said beams of intense light across a space in a predetermined pattern, or a combination of (a) and (b);
- and
- a control circuit connected to said intense light source.
A visual impairment device comprising:
- a power supply;
- a laser light source connected to said power supply and capable of producing two or more laser beams having different peak wavelengths, wherein at least one of said laser beams has a wavelength in the visible range of 400-700 nm;
- a modulator for spatially modulating the two or more beams of intense light in a spatial array such that at least one of said beams in the array has the irradiance to cause visual impairment within 0.25 seconds of light exposure, wherein the spatial array covers an area with a pattern of light beams made by (a) splitting one or more said laser beams into a plurality of beams to produce a pattern of discrete beams separated by a preselected distance, or (b) moving one or more said laser beams across a space in a predetermined pattern, or a combination of (a) and (b);
- and
- a control circuit connected to said laser light source.
A method of creating a visual impairment zone using device, the method comprising:
- activating an intense light source comprising two or more beams of intense light having different peak wavelengths wherein at least one of the beams of intense light has a wavelength bandwidth less than 50 nm,
- modulating the two or more beams of intense light with a modulator to produce a spatial array such that at least one of the beams used to produce the spatial array has the requisite irradiance to cause temporary visual impairment, wherein the spatial array illuminates an area with a pattern of light beams made by (a) splitting one or more said beams of intense light into a plurality of beams to produce a pattern of discrete beams separated by a preselected distance, or (b) moving one or more said beams of intense light across a space in a predetermined pattern, or a combination of (a) and (b)
- thereby creating said visual impairment zone.
