The photoelectric pick-up device for picking up acoustic vibration signals with photoelectric transducing and converting them into electric signals is mainly composed of light emission and photosensitive receiving units with at least one pair of them for each channel. An optical resonant cavity is located before them. When optical transmitter emits a light beam with a constant or stable power, and a vibration or deformation of tested variable is generated and sensed by a sensing system connected with light valve, the amplitude of the light flux received by photosensitive receiver may be changed and then converted into electric signal varying with vibration or deformation by light valve.

Why photoelectric measurement are so sensitive to the nature of photoelectric surface?
Photoelectric measurements are sensitive to the nature of the photoelectric surface because the surface properties, like work function and reflectivity, directly affect the efficiency of electron emission when photons are absorbed. The surface characteristics influence the energy required for electron liberation, impacting the overall photoelectric effect.
Why are photoelectric measurement so sensitive to the nature of the photoelectric surface?
why are photoelectric measurements are so sensitive to the nature of the photoelectric surface
Which phenomenon demonstrates a particle nature of light?
The photoelectric effect demonstrates the particle nature of light. In this phenomenon, light is shown to behave like a stream of particles (photons) by ejecting electrons from a material when it hits the surface.
On what factors does photoelectric current depends?
The photoelectric current depends on the intensity of light shining on the surface, the frequency of the light, the type of material the surface is made of, and the energy of the individual photons. Increasing any of these factors can result in a higher photoelectric current.
How does the light intensity affect the photoelectric current?
Increasing light intensity results in more photons being incident on the photoelectric material, leading to more electrons being ejected, thus increasing the photoelectric current.

What is meant by photoelectric colorimeter?
Photoelectric colorimeter is a medical term. Essentially, it is referring to a colorimeter using a photoelectric cell and appropriate filters instead of the eye.
Match the experimental conditions applied to the photoelectric effect observed.?

Is photoelectric renewable or nonrenewable?
It is considered renewable. It photoelectric energy is created when the sun shines.
What do Photoelectric detectors detect?
Photoelectric detectors are more sensitive to slow, smoldering fires
