FOV Magnification Module

Strucutured Light Module

Virtual, Augmented and Mixed Reality, Autonomous Cars and Medicine are just a sample of the applications which require projection of patterns with very large angles for 3D sensing (Standard Beam Splitters, Random MultiSpot, Dot Generators, Multi-Lines, Homogenizers, Multi-Rings or other custom pattern).

HOLO/OR offers high-angle magnification modules, suitable for all wavelengths and made from Polycarbonate or Glass substrates. These modules are available for a variety of angles, magnifications and different price ranges.

Each module includes a pattern generating Diffractive Optical Element (DOE) and lens-system to provide magnification (without aperture clipping). These modules can be integrated into existing laser systems, with no built-in laser source that limits the customer to a certain wavelength and intensity.

HOLO/OR offers solutions for both rapid prototyping in plastic material, as well as mass production in plastic and glass substrates.
For many applications, the pincushion distortion of the projected pattern is not an issue. However, for applications where this distortion needs to be corrected, HOLO/OR can provide such correction for the plastic module.

360 degrees Projection Module

Holo/Or has developed a novel projection module based on a combination of a DOE and  Catadioptric system. 

This single module project a pattern (dot/ lines or any other) on  a full 360  X 70 degrees field, surrounding the projector. A single passive module with no moving parts,  it enables full mapping of spaces  floor- to ceiling, and can be scales down to compact sizes as required.

Spots density can be controlled an spots number can be adjusted to map the space at any required resolution. more than 100,000 spots is easily achievable. 

Typical  applications:

  •  Autonomous Vehicles 
  • Robot sensing 
  • Drone anti-collision
  • VR/AR space mapping
