example 1

[0146] An example of this device, such as Figure 3A and Figure 3B As shown, it has the following characteristics: a) light beam 1 : CW monochromatic light source at λ1; b) light beam 2,3 : Dual CW monochromatic light sources at λ2 and λ3; c) light beam 4 : broadband CW / pulsed visible light source; d) modulator: beam steering system and integrated optics.

[0147] The system consists of beams emitted in red 1 (single light source) and beams emitted in green and NIR 2,3 (dual light source). Additionally, the system includes beam 4 (broadband CW / pulsed light source), which, when included in the system, causes the light source to switch from a blinding (uncomfortable glare) light source to a disabling (glare, flash blindness) light source (eg, using a CW laser system).

[0148] Figure 3A shows the beam i 102 (where i=1, 2, 3, 4, . . . n). beam i 102 can represent the above beams (beam 1 ,beam 2,3 ,beam 4 etc.) in any beam. Figure 3A Shown is when the beam is p...

example 2

[0153] Another example of the conceived device produces Figure 4 pattern shown. In this device, the beam 1 is at λ 1 , lambda 2 and lambda 3 CW triple laser light source. The modulator includes a diffractive optical element (DOE).

[0154] The system consists of blue light (λ 1 150), green light (λ 2 152) and red light (λ 3 154) Beam emitted 1 , where λ 1 1502 1523 154. beam 1 A broadband CW / pulsed light source can also optionally be included. If a broadband CW / pulsed light source is added to the light source, the system transitions from a blinding (uncomfortable glare) light source to a disabling (glare, flash blindness) light source (eg, with a CW laser system). When using a modulator comprising a DOE, a pattern showing distribution in the space of several wavelengths is produced. Note that the pattern can be static or dynamic. In this example, the irradiance at the entrance of the no-go zone is ≤6x 10 -4 W / cm 2 .

example 3

[0156] Another example of the conceived device produces Figure 5 The pattern shown (only one beam 150). The system consists of a 1 and lambda 2 The CW dual laser source (thus the beam 1 Includes two wavelengths λ 1 150 and lambda 2 156. In this example, the source beam 1 Including green emission and infrared emission, corresponding to λ 1 150 and lambda 2 (not shown). If a broadband CW / pulsed light source is added to the light source, the system transitions from a blinding (uncomfortable glare) light source to a disabling (glare, flash blindness) light source (eg, with a CW laser system). When using a modulator that includes a DOE, a pattern is generated that exhibits distribution in the space of a pair of wavelengths. beam 1 Also included is a reflective light valve (beam steering / grating system) that dynamically moves the light pattern in an elliptical motion 158 .

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 arrayhas 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 673,442, filed May 18, 2018, entitled "Laser Shield Device," the entire contents of which are incorporated herein by reference. technical field Background technique [0003] In the current environment of increased school shootings, effective safety measures are imperative. However, many school and university buildings are constructed to achieve an attractive and open campus style with multiple buildings, multiple entrances and exits, and large windows. Unfortunately, these design configurations are not conducive to security and containment. One security solution is to immobilize or disable a potential shooter or intruder at an entryway or other location for a period of time long enough for law enforcement to respond to the situation. [0004] A well-known phenomenon in aviation is laser-induced visual impairment. High power LEDs and laser...
