Australia has granted patents for new light-bending camouflage technology and laser scattering technology produced by Canadian defence company HyperStealth Biotechnology Corporation.
Australian patents were granted for claims regarding the company’s “Interconnected Lens Materials Arranged as Lens Sheets for Improved Camouflage (Light Bending Material)” on 29 May, and a separate patent application for “System and Method for Laser Scattering, Deviation and Manipulation (Splitting a single laser beam into 10 million beams for advanced LiDAR systems)” on 5 June.
The applications were submitted by HyperStealth president Guy Cramer, according to the documents. The company has previously outlined that its technology renders static objects nearly invisible by bending light around them.
“(The improved camouflage) uses of a lens sheet as a camouflaging agent in various applications. Various embodiments of a lens sheet assembly, methods of making the various embodiments of the lens sheet assembly and methods of using embodiments by placing the assembly between an object to be camouflaged and an observer are disclosed,” according to documents submitted.
“Light from the object undergoes at least one of refraction and reflection such that the object is substantially disguised from the observer.”
HyperStealth has previously acquired patents in India, China, Japan, the United States, and South Africa – according to the company.
“(The laser scattering patent outlines) a system utilizing a lenticular sheet and a laser source projecting a laser beam onto the lenticular sheet produces shapes such as laser cones,” the patent documents said.
“Minor adjustments of the laser source with respect to the lenticular sheet may vary the size and shape of the laser cone that provides for improved light detection and ranging (LiDAR) systems.
“A diffraction grating added in the path of the laser beam causes a laser pattern of a matrix of lines to be produced which also provides for improved interference between multiple lenticular sheets may be used to deviate a laser beam to protect military assets from laser-guided projectiles and/or laser acquisition.”
