Electro Optical System

An electro optical system is a combination of sensors, optics and electronics that detects or manipulates signals in the light spectrum.electro optical system The technology has a wide range of applications in areas such as radar, infrared (IR) and visible imaging, motion control and other military and civilian systems.

Electro optic sensors convert light energy into electrical energy to generate an image or sense information.electro optical system The technology is extremely versatile, with many different sensor types available, each of which has its own unique characteristics and applications. For example, an infrared (IR) camera converts invisible radiation from heat to a visible light signal. These images are then interpreted by an electronic system to determine the temperature of the scene and/or detect objects within it.

An IR sensor has two main parts: the sensor element and the camera lens.electro optical system The sensor element contains a light-sensitive semiconductor, such as an infrared photodetector or a photovoltaic cell. The lens collects and directs the incoming light onto the sensor element, where it is converted to electronic data. The camera lens focuses the sensor’s light beam, either at the object or the surrounding environment.

A sensor can be classified based on its wavelength, size and sensitivity. For example, an IR sensor with an infrared band between 8 and 15 micrometers is known as a mid-wavelength IR sensor or mid-IR band sensor. The sensitivity of an IR sensor is determined by its quantum efficiency (QE), which refers to the percentage of photons that hit the device’s photoreactive surface and produce charge carriers.

The QE of an IR sensor is affected by several factors, including the pixel size, the detector type and the material that makes up the detector. The pixel size is important because it affects the number of photons that are captured. In addition, the detector type and material can impact the spectral response bandwidth of a sensor.

Sensor performance is also influenced by the signal-to-noise ratio. To increase the SNR, a sensor can be improved by decreasing its pixel size. This allows more photons to reach the sensor, which results in a higher image quality and a wider field of view.

Another way to improve a sensor’s performance is to reduce its power consumption. This can be achieved by lowering the operating temperature of the sensor, using lower-cost, low-power pixel technologies or incorporating active cooling into the system.

A key to success in any mission is having the right equipment and systems. That’s why L3Harris provides electro-optical/infrared (EO/IR) sensor systems that are platform and weapon system agnostic and designed to be integrated with customer-selected fire control, consoles and ship systems. Our motion systems are engineered to withstand the pounding of land vehicles, the turbulence of flight and the extremes of space so they can acquire an image quickly and hold it steady. These high-torque, super-steady systems enable EO/IR sensors to deliver critical situational awareness and precision targeting for successful missions worldwide.
