EXTERNAL ILLUMINATION WITH REDUCED DETECTABILITY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18603546 titled 'EXTERNAL ILLUMINATION WITH REDUCED DETECTABILITY

The abstract describes a patent application for an illumination system that emits light into an environment while remaining undetectable to certain external light detection systems. The system includes a single photon avalanche diode (SPAD) low light detection device and a light emitting device that provides illumination with a wavelength of at least 950 nanometers. The intensity of the illumination is set to a level that makes it undetectable from a certain distance. The SPAD LL detection device generates an image of the environment while the illumination is provided.

• The system includes a SPAD low light detection device and a light emitting device.
• The light emitting device provides illumination with a wavelength of at least 950 nanometers.
• The intensity of the illumination is set to be undetectable from a certain distance.
• The SPAD LL detection device generates an image of the environment while the illumination is provided.
• The system enables illumination without being detected by certain external light detection systems.

Potential Applications: - Surveillance systems - Security systems - Night vision technology

Problems Solved: - Providing illumination without being detected - Enhancing surveillance capabilities in low light conditions

Benefits: - Improved stealth capabilities - Enhanced security measures - Better visibility in low light environments

Commercial Applications: Title: Undetectable Illumination System for Enhanced Security This technology can be used in surveillance systems for high-security facilities, military operations, and law enforcement agencies to provide covert illumination without being detected.

Questions about the technology: 1. How does the system ensure that the illumination remains undetectable from a certain distance?

  The intensity of the illumination is set based on the roll-off rate of the light to make it undetectable.

2. What are the potential drawbacks of using a single photon avalanche diode (SPAD) low light detection device in this system?

  SPAD devices may have limitations in terms of sensitivity and range, which could affect the effectiveness of the system.

Original Abstract Submitted

Disclosed herein are techniques for providing an illumination system that emits illumination into an environment while also enabling that system to be undetectable to certain types of external light detection systems. The system includes a single photon avalanche diode (SPAD) low light (LL) detection device and a light emitting device. The light emitting device provides illumination having a wavelength of at least 950 nanometers (nm). An intensity of the illumination is set to a level that causes the illumination to be undetectable from a determined distance away based on the roll off rate of the light. While the light emitting device is providing the illumination, the SPAD LL detection device generates an image of an environment in which the illumination is being provided.
