| 31. | A second photodiode ( or a linear array of photodiodes ) is positioned farther along the length of the sensor.
|
| 32. | The scattered light passes through a special transforming lens system and is collected on a number of concentric photodiode rings.
|
| 33. | ASPs are typically composed of two gratings ( a diffraction grating and an analyzer grating ) above a single photodiode.
|
| 34. | The 1064 nm laser return was split to the LIDAR receiver ( an avalanche photodiode detector ) using a dichroic filter.
|
| 35. | However, EUV photon count is determined by the number of electrons generated per photon that are collected by a photodiode.
|
| 36. | This frameless design is more elaborate than the framed style, relying on reflecting the light back to a single photodiode.
|
| 37. | When the emitted beam bounces off the floor, the reflected energy is almost exclusively concentrated on the first adjacent photodiode.
|
| 38. | TES single-photon detectors suffer nonetheless from a few disadvantages as compared to their avalanche photodiode ( APD ) counterparts.
|
| 39. | The scintillator absorbs the X-rays and converts them into visible light photons that then pass onto the photodiode array.
|
| 40. | Arrays of detectors, such as charge coupled devices ( CCD ) or photodiode arrays ( PDA ) can also be used.
