SENSORS / DETECTORS ABOUT DOCUMENT
LIGHT SENSORS & DETECTORS
A light sensor is a device senses or detects light. Various available kinds of light sensors and detectors function in different ways to give required results.
Active pixel sensors which are image sensors comprises of an integrated circuit with a number of pixel sensors. Each individual pixel has a light sensor as well as an active amplifier.
Charge-coupled devices (CCD)
These are applied in recording of images in astronomy, digital cinematography and digital photography.
A silver halide molecule is split into an atom of metallic silver and a halogen atom; the photographic developer causes adjacent molecules to split similarly. An example is a photographic plate.
They are sensitive enough to measure and determine the energy of single x-ray, visible and infrared photons.
They are normally quantum devices where individual photons produces a discrete effect when exposed to light. This makes Optical detectors to behave like thermometers by responding solely to the heating effect of the incoming radiation.
Photo resistors or Light Dependent Resistors (LDR)
They change resistance according to light intensity. The light then can be measured or determined by measuring the resistance.
Photovoltaic cells or solar cells
When Illuminated they produce a voltage and supply an electric current. Which means the level of illumination is directly dependent on the amount of light being supplied.
They contain a photocathode that emits electrons when illuminated. A chain of diodes then can be used to amplify the electrons.
These contain a photo cathode which when illuminated emit electrons making the tube to conduct an electric current that is proportional to the light intensity.
Has two photodiode arrays which convert light into current; one photodiode array responds to ambient light and the other responds only to infrared light; when joined with an infrared LED, this second LED array can operate as a proximity sensor.
Ambient Light Sensing Application
Ambient light sensors are incorporated in various laptops as well as cell phones to detect the lighting in the surrounding environment and appropriately adjust the backlight of the screen.
