Laser lock imaging method and device

Abstract

The invention discloses a laser lock imaging method and a device, which belongs to the technical field of electronic information and relates to an image processing technique. Periodically modulated laser is adopted to irradiate a target area, partial background light in a target viewing field is filtered by optical filtering and is then processed by phase demodulation which is detected by weak signals, and a target image in the target viewing field is extracted from the strong background light. By using the method and the device, the clear target image can be extracted from the strong background light, and the background light suppression ability is great. The method and the device can be applied to aiming systems in traffic monitoring, industrial monitoring and weapon equipment and night-vision equipment.

AI Technical Summary

Benefits of technology

This patented technology improves how we detect objects without actually measuring them accurately through reflection off their surfaces. It uses filters made up of multiple layers to block unwanted lights like sunlight during certain phases of operation. By doing this, our device becomes more accurate over time because less energy needs to be absorbed compared to traditional methods such as lensless cameras.

Problems solved by technology

Technological Problem: Existing techniques involve capturing images without any clear indications about hidden areas within the subject being observed while avoiding harm caused by external lights like brightness or darkness. Additionally, current cameras suffer from insufficient contrast between dark and non-bright spots during daytime because they lack sufficient sensitivity.
