the third lens together with the second images the directions image on a 2-dimensional optical sensor (e.g., electronic camera). This simple arrangement is the basis for all conoscopic devices (conoscopes). It is not straight forward however to design and manufacture lens systems that combine the following features:

An optical sensor converts light rays into electronic signals. It measures the physical quantity of light and then translates it into a form readable by an instrument. An optical sensor is generally part of a larger system that integrates a source of light, a measuring device, and the optical sensor. This is often connected to an electrical ...
Microoptoelectromechanical systems (MOEMS), also known as optical MEMS, are integrations of mechanical, optical, and electrical systems that involve sensing or manipulating optical signals at a very small size. MOEMS includes a wide variety of devices, for example optical switch, optical cross-connect, tunable VCSEL, microbolometers.
Electronic light sensors. Optoelectronics (or optronics) is the study and application of electronic devices and systems that find, detect and control light, usually considered a sub-field of photonics. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible ...
AAR-47 Sensors mounted on a USMC V-22 Osprey aircraft. The AAR-47 missile warning system consists of 4 Optical Sensor Converters (OSC), a Computer Processor and a Control Indicator. The system is relatively light at a total weight of approximately 32 pounds. [4] There is one optical sensor converter for each side of the aircraft.
In engineering, optomechatronics is a field that investigates the integration of optical components and technology into mechatronic systems. [1] The optical components in these systems are used as sensors to measure mechanical quantities such as surface structure and orientation. [2]
Optical sensors are growing in popularity due to the low-cost, low power requirements and long term stability. They provide viable alternatives to electrode-based sensors or more complicated analytical instrumentation, especially in the field of environmental monitoring [2] although in the case of oxygen optrodes, they do not have the resolution as the most recent cathodic microsensors.
