What is 'Mirror Gain' for a Robot Parabolic Mirror?

Click For Summary
SUMMARY

'Mirror gain' refers to the ratio of light intensity concentrated by a parabolic mirror when it is aligned with a light source. This concept is crucial for applications involving focused light, such as in robotics and optical systems. The gain can be expressed as a simple ratio of intensities or as a logarithmic value, depending on the desired representation. Understanding mirror gain is essential for optimizing the performance of robotic systems utilizing parabolic mirrors.

Hi,

I've asked someone to make me a parabolic mirror for a robot and they want to know the 'mirror gain' i would like. Does anybody know what 'mirror gain' is?

thanks

If the mirror is pointing straight back at the light source, the light will be "concentrated" if you will, onto a smaller projected area, but with a greater intensity, directly back in the direction it came. Think of the bright flash you get instantaneously from a lighthouse or fire engine warning light. The gain is just the ratio of the two intensities. (Although, depending on how you want to express the gain, it may be a log of this ratio).
