How can I introduce a voltage controlled variable delay in the path of a mono-chromatic light beam? That is, how can I phase modulate the light?
Thank you in advance for your input!

VCVD is a type of electronic circuit that is designed to delay a signal by a variable amount of time, controlled by an input voltage. It is commonly used in audio and video equipment to create effects such as echo or reverb.
The circuit consists of a delay line, which is essentially a series of capacitors and resistors. The input signal is fed into the delay line, where it is stored for a brief period of time before being output. The amount of time the signal is delayed depends on the voltage level applied to the control input.
VCVD allows for precise and real-time control of the delay time, which can be useful in creating complex and dynamic audio effects. It also eliminates the need for multiple fixed delay circuits, making it more compact and cost-effective.
VCVD is commonly used in audio effects processors, guitar pedals, synthesizers, and other musical equipment. It can also be used in video equipment for special effects or in communication systems for signal processing.
One limitation of VCVD is that it can introduce some signal distortion, particularly at higher delay times. It also requires a stable and accurate control voltage to achieve precise delay times. Additionally, VCVD circuits can be complex and may require advanced knowledge of electronics to design and troubleshoot.
