Rafale EOTS
Optronique secteur frontal
OSF is visible upfront, beside the refueling boom.
The OSF (Optronique secteur frontal) is a long range Optoelectronics system developed for the French Dassault Rafale combat aircraft.
With its narrow field, the visible waveband capability is truly valuable to identify targets in situations where visual contact is required by the rules of engagement.[1]
It allows target tracking, through IR (Infra-red search and track) and visual sensors:
F-35 Lightning II (EOTS)
The Electro-Optical Targeting System (EOTS) for the F-35 Lightning II is an affordable, high-performance, lightweight, multi-function system that provides precision air-to-air and air-to-surface targeting capability. The low-drag, stealthy EOTS is integrated into the F-35 Lightning II's fuselage with a durable sapphire window and is linked to the aircraft's integrated central computer through a high-speed fiber-optic interface.
As the first sensor to combine forward-looking infrared and infrared search and track functionality, EOTS enhances F-35 pilots’ situational awareness and allows aircrews to identify areas of interest, perform reconnaissance and precisely deliver laser and GPS-guided weapons. Lockheed Martin has delivered more than 300 systems for the F-35 Lightning II.
Advanced EOTS, an evolutionary electro-optical targeting system, is available for the F-35’s Block 4 development. Designed to replace EOTS, Advanced EOTS incorporates a wide range of enhancements and upgrades, including short-wave infrared, high-definition television, an infrared marker and improved image detector resolution. These enhancements increase F-35 pilots’ recognition and detection ranges, enabling greater overall targeting performance.

J-31 IRST
Beijing tech show highlights advances in Chinese fighter sensors
China's Jiangsu A-Star Aviation Industries Company (A-Star) used the first Beijing exhibition promoting "civil-military integration" to reveal new combat aircraft electro-optical systems, some of which may be slated for the country's fifth-generation fighters.

A-Star's booth featured images of a Shenyang Aircraft Corporation J-31 fifth-generation export fighter to highlight two electro-optical systems, although it is not clear that A-Star's systems will equip future developments of this fighter, revealed as the FC-31 at the November 2014 Zhuhai Air Show.
A-Star's EORD-31 appears to be a conventional infrared search and tracking (IRST) system but with a faceted sensor dome; and the claimed ability to detect a F-22. (Via Top81 web page)
The EOTS-89 resembles the Electro-Optical Targeting System (EOTS) of the Lockheed Martin F-35, which combines Forward Looking Infrared and Infrared Search and Track (IRST) capabilities. The similarity includes the use of two tracking mirrors and a flat-facetted optical window, with bottom fuselage placement just aft the radar radome. Such a system was so placed on the large mock-up of the FC-31 seen in November 2014.
The AUEODS system by A-Star uses two wingtip mounted pods that combine a domed IRST with a conventional targeting pod. (Via Top81 web page)
Shown placed on the front starboard side of the J-31 canopy, A-Star's EORD-31 serves as an IRST, similar to the OLS-27 series used by the Russian Sukhoi Su-27 fighter. However, instead of a spherical dome cover, the EORD-31 is flat and facetted. Chinese press reports claimed the system may be able to detect a Lockheed Martin F-22A at 110 km and a Boeing B-2 at 150 km.
Also on display was an image of A-Star's "AUEODS" system, which uses TX-S55 and TX-S56 pods which combine a conventional targeting pod with an over or under-mounted domed IRST. These two pods were shown on a Su-27 on the wingtip position taken by SORBITSYA electronic warfare pods.
A promotional image from A-Star indicated that its new F-80 medium range air-to-air missile may have a ground attack capability. (Via Top81 web page)
Chinese press reports claimed it can detect targets out to 200 km, or 70 km for the F-22A and 120 km for the B-2. The reports also claim it can detect a Tomahawk cruise missile out to 18 km.
A-Star used the 2014 Zhuhai Air Show to reveal its F-80 medium-range air-to-air missile with a unique five flat facet for its infrared/imaging seeker. While its range has not yet been disclosed, A-Star used the recent Beijing exhibition to indicate it has a ground-attack capability.

With its narrow field, the visible waveband capability is truly valuable to identify targets in situations where visual contact is required by the rules of engagement.[1]
It allows target tracking, through IR (Infra-red search and track) and visual sensors:
- on the left, the main IR detector can be used as FLIR (to send a video signal to the pilot), or to detect:
- air targets at ranges up to 100 kilometers
- surface or sea targets at up to 6 kilometers
- on the right a TV/IR sensor for target identification (40 km range) including laser rangefinder.[2]
- passive long-distance detection
- target identification before engagement
