Exampling Cloaking Device

SPACE1 Tests Small Exampling Optical Cloaking Device

The original SPACE1 cloak is real and runs on optical lenses defined by the mathematics in the original post and is designed to make large spaceships appear or disappear, as shown in Star Trek.

However, there's a more simple way to create an exampling cloak without the number of glass optical lenses set to calibrated focal lengths. Using a single flat 2D-appearing sheet of lenticular resin the shape of a credit card and a pen to represent the spacecraft or rocket, a mechanical calibration either shows the object or puts it into full cloak.

This is a type of Fresnel lens that takes the light coming into it from the back at obtuse angles and projects it forward in the front of the lens. 

Simplifying Cloaking Technology

This re-directing of lightwaves causes what is on either side of the lens to appear as though it is directly behind the lens, effectively making what’s actually behind the lens to seemingly disappear. Larger sample cloaking devices can be made from sheets of 3D Lenticular resin lenses imported from China. A Lubor’s lens is more correctly called a lenticular lens which consists of an array of identical linear prisms usually molded into a sheet of clear plastic. A Fresnel lens consists of an array of circular prisms whose angles increase and widths narrow with distance from the center. A linear Fresnel lens would have the increasingly refractive prisms in a linear array to form a line focus. The original Fresnel lenses, named after the inventor—a famous French optics guy, were first used in lighthouses to collimate searchlight beams, while modern usage is often found using molded plastic sheets used in solar cookers and other applications where a flat lens is desirable. The Lubor’s lens is used in ‘invisibility cloak’ demonstrations, and is named after the magician who promoted the effect.

Lenticular Lens Design

A lenticular lens design allows very high powered convex or concave lenses to be used in situations when lens size, thickness, or weight, would otherwise be problematic. Lenticular lenses are often used for eyeglasses when the lens powers are >+/-15.00D. The optical portion of the lens is molded to a flat “carrier” lens that is usually close to plano, or zero, in power. Below is an example of a very high plus lens in lenticular design. You can see that the strong Rx is only in the circular area at the lens center.

Fresnel Design

Another way to put very high powered lenses into a thinner configuration is to use a “Fresnel” design. This involves using multiple small lenses placed over a flatter “carrier” lens. This is most commonly used for magnification (convex or plus powered lenses), or for prism lenses (wedge shaped lenses that move the location of an image rather than change its size). The cross-section image below illustrates a Fresnel lens that incorporates multiple small prisms instead of one very thick prism. While this design has many optical and industrial applications, it is only used for prism in ophthalmic lenses. The lines created by the prisms can interfere somewhat with lens clarity.

Lubor Lensing

A Lubor lens is a variation of a Fresnel prism lens design, and like any linear prism it will deviate the image in one direction, and along one axis only. If the lens is oriented so that the horizontal lines are parallel with the object being viewed, that image will be moved forward and be visible, but any objects in the meridian 90° away, will be blocked (and vice versa). Lubor lenses are used primarily by magicians! 

Buying Lenses

You don’t make a Fresnel lens, you buy them. They are mostly made of glass and clear plastic materials such as acrylic and polycarbonate. They work by stepping the surface of the lens to remove the mass that would make a normal lens very thick if the lens surface was continuous.

Space1 Cloaking Technology

Optical and Physical Derivation & Invention of Space1 Cloaking Technology for Spacecraft & Starships

Using ideas from Optics, Physics, and Romulan Star Trek scifi technology, Humanoido at SPACE1 has invented the CLASSIFIED cloaking device for starships. The derivation of Snell's Law from optics and physics predicts degrees of invisibility. (see ray tracing figure) Romulans of scifi Star Trek used the above configuration for a cloaking device. However, SPACE1 is adopting optics which itself is transparent.

The Cloak provides an optical and electromagnetic radiation invisibility shield to spacecraft flown as starships. The shield is physically implemented and the craft maintains a specific calculated orientation to the line of invisibility when the cloak is brought online. The starship hull contains the cloak material from which it's lined. The SPACE1 starship cloak optically refracts light around the starship creating a cloak of invisibility. More testing of the Cloak is needed in hot and cold environments, as the working prototype is operating across room temperature and end to end extremes. 

Formulae derivation is from a Computer Math program I wrote at the University and is based on both the derivation and real time implementation of Snell's Law, with graphical representation, on an IBM mainframe computer. In its simplest form, Snell's law can be derived from Fermat's principle, which states that the light travels the path which takes the least time. By taking the derivative of the optical path length, the stationary point is found giving the path taken by the light.

Deriving a working example of Snell's law for a stealth cloaking device, light from medium 1, point Q, enters medium 2, refraction occurs, and reaches point P finally. Assume the refractive index of medium 1 and medium 2 are {\displaystyle n_{1}}n_{1} and {\displaystyle n_{2}}n_{2} respectively. Light enters medium 2 from medium 1 via point O. {\displaystyle \theta _{1}}\theta _{1} is the angle of incidence, {\displaystyle \theta _{2}}\theta _{2} is the angle of refraction with respect to the normal. The phase velocities of light in medium 1 and medium 2 are v_1=c/n_1 and {\displaystyle v_{2}=c/n_{2}}v_2=c/n_2 respectively.

{\displaystyle c}c is the speed of light in vacuum. Let T be the time required for the light to travel from point Q through point O to point P.

{\displaystyle T={\frac {\sqrt {x^{2}+a^{2}}}{v_{1}}}+{\frac {\sqrt {b^{2}+(l-x)^{2}}}{v_{2}}}={\frac {\sqrt {x^{2}+a^{2}}}{v_{1}}}+{\frac {\sqrt {b^{2}+l^{2}-2lx+x^{2}}}{v_{2}}}}{\displaystyle T={\frac {\sqrt {x^{2}+a^{2}}}{v_{1}}}+{\frac {\sqrt {b^{2}+(l-x)^{2}}}{v_{2}}}={\frac {\sqrt {x^{2}+a^{2}}}{v_{1}}}+{\frac {\sqrt {b^{2}+l^{2}-2lx+x^{2}}}{v_{2}}}} where a, b, l and x are as denoted in the long derivation, x being the varying parameter.

To minimize it, one can differentiate:

\frac{dT}{dx}=\frac{x}{v_1\sqrt{x^2 + a^2}} + \frac{ - (l - x)}{v_2\sqrt{(l-x)^2 + b^2}}=0 (stationary point). Note that {\displaystyle {\frac {x}{\sqrt {x^{2}+a^{2}}}}=\sin \theta _{1}}\frac{x}{\sqrt{x^2 + a^2}} =\sin\theta_1

and {\displaystyle {\frac {l-x}{\sqrt {(l-x)^{2}+b^{2}}}}=\sin \theta _{2}}\frac{  l - x}{\sqrt{(l-x)^2 + b^2}}=\sin\theta_2. Therefore,

{\displaystyle {\frac {dT}{dx}}={\frac {\sin \theta _{1}}{v_{1}}}-{\frac {\sin \theta _{2}}{v_{2}}}=0}\frac{dT}{dx}=\frac{\sin\theta_1}{v_1} - \frac{\sin\theta_2}{v_2}=0

{\displaystyle {\frac {\sin \theta _{1}}{v_{1}}}={\frac {\sin \theta _{2}}{v_{2}}}}{\displaystyle {\frac {\sin \theta _{1}}{v_{1}}}={\frac {\sin \theta _{2}}{v_{2}}}}

{\displaystyle {\frac {n_{1}\sin \theta _{1}}{c}}={\frac {n_{2}\sin \theta _{2}}{c}}}\frac{n_1\sin\theta_1}{c}=\frac{n_2\sin\theta_2}{c}

{\displaystyle n_{1}\sin \theta _{1}=n_{2}\sin \theta _{2}}n_1\sin\theta_1=n_2\sin\theta_2

The Cloak will be installed on the hull of the super spacecraft or super starship version of the Super Rocket. SPACE1 has completed a transporter and is working on shields, phasers, and photon torpedos. The Cloak will allow SPACE1 to work and perform starship experiments in space without drawing significant attention.
