MOE-based illumination projector - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240094437 titled 'MOE-based illumination projector

Simplified Explanation

The optoelectronic apparatus described in the patent application includes an array of emitters that emit beams of optical radiation. An optical substrate is mounted over the array, and an optical metasurface is placed on the substrate. The metasurface is designed to collimate and split the emitted beams into groups of collimated sub-beams, directing them towards a target to create a pattern of spots.

• Array of emitters emitting beams of optical radiation
• Optical substrate mounted over the array
• Optical metasurface on the substrate collimating and splitting beams into sub-beams
• Sub-beams directed towards a target to form a pattern of spots

Potential Applications

The technology described in the patent application could be used in various applications such as:

• Laser cutting and engraving
• Optical communication systems
• LiDAR systems for autonomous vehicles

Problems Solved

The optoelectronic apparatus addresses the following issues:

• Efficient collimation and splitting of optical beams
• Precise targeting and spot formation on a surface

Benefits

The benefits of this technology include:

• Improved accuracy and precision in beam manipulation
• Enhanced performance in optical systems
• Increased efficiency in target illumination

Potential Commercial Applications

The technology has potential commercial applications in:

Possible Prior Art

One possible prior art for this technology could be the use of diffractive optical elements in beam shaping and manipulation.

How does the optical metasurface achieve collimation and splitting of the emitted beams?

The optical metasurface uses nanostructures to control the phase and amplitude of the incoming light waves, allowing for precise manipulation of the beams.

What materials are used in the construction of the optical substrate and metasurface?

The optical substrate is typically made of glass or other transparent materials, while the metasurface is composed of nanostructured materials such as silicon or gold.

Original Abstract Submitted

an optoelectronic apparatus includes an array of emitters configured to emit beams of optical radiation. an optical substrate is mounted over the array. an optical metasurface is disposed on the optical substrate and configured to collimate and split each of the emitted beams into a respective group of collimated sub-beams, and to direct the collimated sub-beams toward a target to form a pattern of spots on the target.
