A photoelectric sensor, or photo eye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are used extensively in industrial manufacturing. There are three different functional types: opposed (through beam), retro-reflective, and proximity-sensing (diffused).
Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications, for example: Lamps that turn on automatically in response to darkness. Position sensors that activate when an object interrupts a light beam.

What detects the presence or absence of a mark in a predetermined place?
A sensor or detector is typically used to detect the presence or absence of a mark in a predetermined place. These devices can use various technologies such as photoelectric sensors, proximity sensors, or vision systems to detect the mark accurately.
What are photoelectric sensors used for?
Photoelectric sensors are commonly used for detecting the presence, absence, or distance of an object without physical contact. They are used in various applications such as factory automation, packaging, assembly line, and material handling to detect objects, count objects, and monitor processes.
What is the maximum Sensing frequency of photoelectric sensors?
The maximum sensing frequency of photoelectric sensors can vary depending on the specific model and manufacturer. However, typical sensing frequencies can range from a few hundred Hz to several kHz. It is important to check the datasheet or specifications of the sensor to determine its maximum sensing frequency.
What are optical sensors used for?
Optical sensors are used to detect and measure light levels, colors, distances, and patterns. They are commonly used in cameras, barcode scanners, medical devices, and industrial automation systems for tasks such as detection, sorting, and monitoring.
How traffic signals use photoelectric effect?
Traffic signals use photoelectric sensors to detect the presence of vehicles at intersections. These sensors emit a beam of light, and when a vehicle passes through the beam, it blocks the light, triggering the signal to change. This system enables traffic signals to efficiently control the flow of traffic at junctions.
What is the difference between a laptop wireless optical mouse and a wireless laser optical mouse?
The laser wireless optical mouse has laser sensors to direct the mouse on the screen as without it is a roll ball used to do so.
What detects the presence or absence of a mark in a predetermined place?
A sensor or detector is typically used to detect the presence or absence of a mark in a predetermined place. These devices can use various technologies such as photoelectric sensors, proximity sensors, or vision systems to detect the mark accurately.
What is the difference between optical and radio?
Optical telescopes use either lens' (refractory) or mirrors (reflective) to magnify light. Radio telescopes use dishes to pick up radio waves. sensors on the dishes collect the waves and turn them into a picture
Can an optical mouse that uses optical sensors be placed on nearly all types of flat surfaces?
Yes you can

Where can I find information on optical sensors online?
There is a pretty well-populated list of optical sensor manufacturers at http://www.sensorsportal.com/HTML/SENSORS/OptoSens_Manufacturers.htm for starters. Also, another rather large list of manufacturers and suppliers is located here: http://www.thomasnet.com/products/optical-sensors-73749350-1.html. As for information on them, wisegeek.com has a good article on them here: "http://www.wisegeek.com/what-is-an-optical-sensor.htm" Hope this helps!

What are the main characteristics of microwave remote sensing and optical remote sensing?
Optical remote sensing is affected by cloud covers , rain etc but microwave remote sensing is not.However the optical sensors always need sun as a source of illumination while active microwave sensors don't need.

What is applications of photoelectric effect in our daily life?
It is in the digital cameras, image sensors, and night vision devices that are widely used in the present world.
How can you tell the difference between a digital sensor and an analog sensor?
Analogue sensors are usualy more accurate :P
