Endoacustica has introduced a high-performance Laser Microphone (Product Code: LAS-MIC), a precision surveillance tool designed for non-intrusive audio collection in sensitive environments. Utilizing advanced optoelectronic technology, the system detects microscopic vibrations on window glass caused by indoor conversations and converts them into intelligible audio without requiring physical access or device placement inside the target area. The system operates by directing an invisible infrared laser beam (790nm wavelength) at a window from a distance of up to 200 meters. As sound waves inside the room vibrate the glass, the reflected beam carries these modulations back to a receiver unit. A photodetector then translates the optical signal into electrical audio, which is processed through proprietary filtering algorithms to enhance clarity and reduce ambient noise interference. Designed as a complete field-ready solution, the LAS-MIC includes matched transmitter and receiver modu
