laser microphone

professional laser microphone, Listen Through Any Window From 1 Full Mile Away!

 

This Laser microphone system is operated by transmitting an invisible IR-beam to the window of the target room. The window pane is slightly vibrating in accordance to the sound waves emanating from speech.

The beam is reflected from the window pane according to the law of optics, ie. the angle of incidence is equal to the angle of reflection. The receiver picks up the reflected beam that is modulated by the window pane vibrations, and the optical signals are automatically converted into electronic signals.

The picked up speech is now filtered, amplified and recorded. Both the transmitter and the receiver are built into standard single lens reflex cameras, allowing for perfect concealment.

The complete system is supplied in a camera case incorporating amplifier, filters and recorder.

LASER MICROPHONE consists of three parts:

  • Laser Transmitter
  • Laser Receiver
  • Amplifier Unit with Audio-Recorder

TRANSMITS/RECORDS

Sound wave vibrations which reflect off smooth-surface glass (single or double glass thermo pane). Transmitter laser's angle of incidence equals the angle of reflection to the receiver. Rippled or grained glass will not provide a suitable reflecting surface from which to record.

FILTERS OUT

Acoustic interference cause by interior and exterior sound wave reflections may be filtered and modulated by the LAS-MIC 's receiving system. The transmission may be fine-tuned by means of a modulated search tone or by adjusting the placement of the receiver. Tape recordings may be further edited at the user's option.
