However, a little reflection shows that this view of the quantum theory of light detection is very far from the truth indeed.
Langley designed two special-purpose light detection and ranging (lidar) sensors.
This enhances light detection but lowers resolution.
It may be involved in light detection, and may have a role on food detection and mating.
Under such conditions, melanopsin acts as a sensory photopigment, performing physiological light detection.
This capability has been demonstrated and used in a variety of applications including ambient light detection and bidirectional communications.
They developed a low-current electric soil humidity sensor which uses light detection to control water pipe valves and improve irrigation efficiency.
Likewise, animals developed the sense of light detection which then progressed to black-and-white vision.
And it invites the conclusion that rhodopsin-like compounds are a particularly favoured way of going about light detection in the animal world.
The group has developed a new type of lidar (which stands for light detection and ranging) for the experiment.
