Optical Sensors - Phototransistors are semiconductor devices that integrate photoelectric conversion and transistor amplification functions. Its core lies in combining the photoelectric conversion characteristics of photodiodes with the current amplification characteristics of transistors, generating photocurrent through light irradiation, and amplifying the photocurrent with the help of transistor structure. Phototransistors have characteristics such as high sensitivity, fast response, low noise, and wide spectral response range, making them particularly suitable for detecting and amplifying weak optical signals. Its design principle is based on the photoelectric effect and the working principle of bipolar transistors. By optimizing material selection and process technology, it achieves efficient and stable photoelectric conversion and signal amplification.
