1. Market Definition & Core Functionality

• What are Photoelectric Detectors? Photoelectric detectors are devices that convert light (photons) into electrical signals. They detect the presence, intensity, or other properties of light. These devices leverage the photoelectric effect, a quantum phenomenon where light incident on certain materials can cause the release of electrons.
• Core Functionalities:
• Light Detection: Sensing the presence of light or specific wavelengths.
• Light Intensity Measurement: Measuring the strength of a light source.
• Color Detection: Discriminating between different colors of light.
• Position/Distance Measurement: Measuring distance by analyzing the properties of the reflected light.
• Object Detection: Sensing presence or absence of objects or specific patterns, or detecting location of an object.
• Proximity/Motion Detection: Sensing if something is near or is moving (using infrared light reflection based sensing)
• Types of Photoelectric Detectors (key categorization criteria based on structure):
• Photodiodes (PIN & Avalanche): Silicon based structures based on p-n or metal insulator semiconductor junctions, high response speeds. Typically for general sensing needs in visible/IR ranges, can measure intensity based on current (generated via photon interaction in semiconductor materials).
• Phototransistors: Have integrated transistor gain (higher light current)
• Photomultiplier Tubes (PMTs): Capable of very high gain (single photon detection), based on amplification principle. Can also distinguish wavelengths if suitable filters are employed before the photo-emissive component of the light collection architecture. For very weak light / specialized scientific use, and used primarily for visible spectrum measurements
• Photoconductive Cells/Photodiodes (CdS, CdSe): Low Cost devices with resistance variation according to light illumination. Suited for intensity changes not fast signals. Have slower operation speeds, used in some cost sensitive consumer applications or in ambient light sensors.
• Photocells: Often a broader term that incorporates all such structures that make the above functionalities based on various types. Often made of several stacked multi-junction (high-performance / higher light capturing devices), to capture maximum possible signal out from incident light. Also useful to selectively block particular wavelengths
• Image Sensors (CMOS/CCD): Detect light across 2D /3D space. CMOS is lower power (most ubiquitous for cameras) while CCD provides a greater light sensing sensitivity
• Infrared detectors
• Thermoelectric sensor: Detect temperature via resistance / thermal changes induced by incident radiation on heat sensitive device structure
• Microbolometers: a variation on thermometric sensor which use temperature dependent resistance for detection of light across all parts of EM spectrum especially on higher end frequencies / wavelengths including in Terahertz regions
• Photon Detector (cooled sensors based on quantum mechanical concepts that absorb light). Also designed for use over very small bandwidth or even single frequency of radiation (to detect molecules by specific light signature absorptions), very sensitive specialized scientific/ instrumentation. Designed to operate under specific and lower temp or in vacuum and in other special operational conditions.
