Charge-coupled devices in astronomy (AQA A-Level Physics): Flashcards

Semiconductor sensor converting light to digital data

Tiny rectangular areas that collect charge from light

Charge is directly proportional to brightness

$\frac{\text{detected}}{\text{incident}} \times 100\%$

4-5%

Less than 10%

Can exceed 80%

200 nm to over 1100 nm

Smaller pixels

1-2 arcminutes
