A bolometer is __________________?
Correct answer: C. Both A. & B.
- A. Used for the measurement of thermal radiation
- B. An element which senses optical input and delivers thermal output
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
A bolometer detects radiant or optical energy through the heating it produces, so it is used for measuring thermal radiation and acts as an optical-to-thermal detector. Thus both descriptions apply.
