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

This abstract first appeared for US patent application 20240219734 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 emits light with a wavelength of at least 950 nanometers. The intensity of the light is set at a level that makes it undetectable from a certain distance based on the roll-off rate of the light. The SPAD LL detection device generates an image of the environment while the light emitting device is providing illumination.

Commercial Applications: Title: Stealth Illumination System for Enhanced Surveillance and Security This technology can be used in surveillance cameras, security systems, military operations, wildlife observation equipment, and astronomical devices to provide undetectable illumination in various environments.

Questions about the technology: 1. How does the SPAD LL detection device work in conjunction with the light emitting device? 2. What are the potential limitations of using light with a wavelength of at least 950 nanometers for illumination in different environments?

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.
