AI Thread Summary
Panchromatic images are sensitive to all visible colors of the spectrum and are often associated with higher resolution compared to multispectral images, which capture data across specific bands but at a lower resolution. While panchromatic images can be black and white, they are not identical to traditional black and white films, as they are sensitive to red light. In remote sensing technology, panchromatic imaging is utilized for detailed analysis, while multispectral imaging is used for capturing more diverse spectral information. The distinction lies in their applications, with panchromatic images offering finer detail and multispectral images providing broader spectral data. Understanding these differences is crucial for effective remote sensing analysis.

Hi,sometimes I read words like panchromatic images in remote sensing technology. Is panchromatic identical with black&white?Owen
 
Physics news on Phys.org
Panchromatic is a b/w film that is red-sensitive. Older, orthochromatic films, are also b/w, but red-insensitive.
 
The definition I get from google is that panchromatic is: (of photographic film) sensitive to all visible colors of the spectrum. Not sure what it means when it comes to remote sensing technology. I'll try to look up more information when I have the time.
 
Some remote sensing systems provide two modes: panchromatic with a higher resolution and multispectral with a lower resolution, so panchromatic is always related to higher resolution.Owen
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
