It is an electronic musical interface which resembles the ancient musical string instrument "Harp".
- Frameless design ("Infinite beam")
- Has several laser beams,each designating a musical note, played by blocking the rays of the beam
- A single beam is split to several ones in a fan fashion using one laser source and a mirror mounted on a stepper motor
- Relies on detection of note to be played from beam obstructed with the help of a photodiode
- Depending on the position of stepper motor at the time of obstruction,the musical note is played
- Playing the actual sound is handled by connecting the laser harp to a synthesiser, in our case a freeware FL studio
