2020年10月1日 · We present “infrared Fish Observation” (iFO), an open-source low-cost underwater infrared (IR) video observation system using high power LEDs and low-cost CMOS camera modules. The use of IR-video surveillance at night is very common for onshore applications and therefore hardware became very efficient at low-cost.

2020年10月1日 · We present ‘‘infrared Fish Observation” (iFO), an open-source low-cost underwater infrared (IR) video observation system using high power LEDs and low-cost CMOS camera modules.

In 1896, two German scientists, Köttgen and Abelsdorff, made a curious observation: when they measured the absorption properties of visual pigments (the molecules that mediate light sensation) extracted from the eyes of freshwater fish, they found them to be ‘red-shifted’ towards longer wavelengths than those of marine fish and land animals.

2015年11月1日 · Intensity of reflected NIR light can be used for 3D fish tracking in tanks. Infrared reflection (IREF) system for fish behavior monitoring is described. The system evaluation showed sufficient accuracy for aquaculture applications. Using IREF system in aquaculture can increase fish production and reduce expenses.

Perceptive Mechanism: At its core, the Flying Fish IR Sensor harnesses the power of infrared radiation to detect subtle variations in its surrounding environment. Through a meticulous interplay of intricate mechanisms, it discerns nuances imperceptible to the human eye, translating them into actionable insights.

2015年11月6日 · Just as research shows saltwater fish can see UV light in the blue sea, scientists have recently discovered freshwater fish can see infrared. A new research sheds light on mechanism behind their special ability to see IR light, which fish use to navigate and hunt.

2012年12月13日 · There is new evidence that some fish (perhaps all) can perceive infrared light. In the Dec issue of PFK there is an article on a new discovery that a species of fish [don't have the issue at home, and can't remember the species, sorry] is sensitive to infrared light.

2021年12月3日 · Imaging technology based on fish eyes could produce lower-energy, more compact, versatile, and sustainable infrared visualization devices of many kinds. It could help robots navigate in dark waters to clean oil spills, study inaccessible ecosystems, and guide smart fishing nets to avoid capturing threatened species.

2012年10月29日 · Biologists from the University of Bonn have discovered that the cichlid fish Pelvicachromis taeniatus can see in the near infrared range; this was thought to be unlikely until now. Seeing in the...
