How do instruments calculate things using absorption of light?

Click For Summary

Discussion Overview

The discussion centers around how instruments utilize the absorption or reflection of light to calculate specific properties of objects. Participants are exploring the mathematical frameworks and algorithms involved in these processes, as well as seeking examples of such devices.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant questions the mathematical basis of algorithms used in light absorption and reflection measurements, seeking clarification on whether calculus is involved.
  • Another participant reiterates the initial question and requests an example of a device that employs these principles.
  • A third participant shares a link to a video about a specific molecular sensor, suggesting it as a relevant example.
  • Another participant recommends searching for "differential reflectometry" as a potential method related to the topic.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as participants are exploring different aspects of the topic without settling on a definitive answer or agreement regarding the mathematical methods involved.

Contextual Notes

Participants have not specified the assumptions underlying their questions or claims, and the discussion lacks detailed mathematical explanations or definitions that could clarify the algorithms mentioned.

Supposedly devices use special algorithms to determine specific things about an object by its absorption or reflection of light, how exactly would such equations work? (if this isn't calculus then please tell me and ill post it somewhere else, i wasn't sure what type of mathematics this would be)

Provide an example of a device of that kind.

Google "differential reflectometry", for instance
