SPATIAL LIGHT MODULATOR AND LIDAR APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17747441 titled 'SPATIAL LIGHT MODULATOR AND LIDAR APPARATUS INCLUDING THE SAME

Simplified Explanation

The abstract describes a spatial light modulator and a LiDAR apparatus that includes the spatial light modulator. The spatial light modulator consists of multiple layers, including a first reflective layer, a second reflective layer with grating structures, a resonance layer, and a filling layer with a low heat transfer coefficient.

• The spatial light modulator includes a first reflective layer.
• It also includes a second reflective layer with multiple grating structures.
• A resonance layer is provided between the first and second reflective layers.
• The filling layer surrounds at least one grating structure and has a low heat transfer coefficient.

Potential applications of this technology:

• LiDAR systems for autonomous vehicles and robotics.
• Optical communication systems.
• 3D scanning and imaging technologies.

Problems solved by this technology:

• Improves the efficiency and accuracy of LiDAR systems.
• Enhances the performance of optical communication systems.
• Enables high-resolution 3D scanning and imaging.

Benefits of this technology:

• Increased sensitivity and resolution in LiDAR systems.
• Improved data transmission and signal quality in optical communication.
• Enhanced precision and detail in 3D scanning and imaging.

Original Abstract Submitted

A spatial light modulator and a light detection and ranging (LiDAR) apparatus including the spatial light modulator are provided. The spatial light modulator includes: a first reflective layer; a second reflective layer comprising a plurality of grating structures spaced apart from each other; a resonance layer provided between the first reflective layer and the second reflective layer; and a filling layer having a heat transfer coefficient of about 100 mW/mK or less and being in contact with an upper surface of the resonance layer while surrounding at least one grating structure of the plurality of grating structures.
