什么是昆虫的复眼？
发布日期：2023年07月16日 分类：生物科学
昆虫的复眼是它们特有的视觉器官，与我们人类的简单眼睛或脊椎动物的复眼有所不同。复眼由许多小而透明的单位眼组成，每个单位眼都包含一个光感受器和一个透镜。这些单位眼被称为“节片”，与相邻节片之间形成了一个规则的六边形网状结构，从而形成整个复眼。
这些光感受器称为“ommatidia”，每个ommatidium都相互独立，可以独立地感知光线。每个ommatidium的前部是一个小透镜，它们收集并聚焦光线，进一步传递给视觉神经系统。
由于复眼是由许多小眼组成的，它们对光线的感知较为分散。这使得昆虫复眼能够快速地感知光和运动的变化，快速反应危险或捕食的机会。由于每个ommatidium的视域略有偏移，昆虫能够获得广阔的视觉范围，几乎可以看到360度。
昆虫的复眼通常比人类的单眼视野大得多，但它们的分辨率相对较低。这意味着昆虫可以将视野扩展到更大范围，但无法像我们一样看到细节。然而，复眼对昆虫的生存至关重要，它们可以追踪食物、寻找伴侣和避免威胁。
总的来说，昆虫的复眼是一种独特而精巧的视觉器官，通过分散感光单元实现了广阔的视野和快速的光感知能力，使昆虫能够在复杂的环境中生存和繁衍。

What are compound eyes in insects?
The compound eyes of insects are unique visual organs that differ from the simple eyes of humans or the compound eyes of vertebrates. The compound eyes are composed of many small and transparent unit eyes, each containing a photosensitive receptor and a lens. These unit eyes, called "ommatidia," form a regular hexagonal lattice structure with adjacent ommatidia, creating the entire compound eye.
These photosensitive receptors collect and focus light through small lenses in the front of each ommatidium, independently perceiving light. The light signals are then transmitted to the visual nervous system.
Due to the composite nature of the compound eyes, the perception of light is more dispersed. This allows insects with compound eyes to quickly perceive changes in light and movement, responding rapidly to potential dangers or opportunities for predation. Because each ommatidium has a slightly different field of view, insects can have a broad visual range, almost reaching 360 degrees.
The compound eyes of insects typically have a much larger field of view than a single human eye, but their resolution is relatively low. This means that insects can expand their field of view to a larger extent but cannot see details as we do. Nevertheless, compound eyes are crucial to the survival of insects as they enable them to track food, find mates, and avoid threats.
In summary, the compound eyes of insects are unique and sophisticated visual organs that provide a wide field of view and rapid light perception through dispersed photosensitive units. These capabilities allow insects to thrive and reproduce in complex environments.
