LED injected light measurements
Setup: - scintillator sheets number from bottom to top in sensor image: 51, 31, 50, 52, 34, 44, 53, 47, 33, 54, 46, 42, 55, 45, 38, 36, 43, 32, 48, 41, 8, 39, 40, 37, 35, 49, 9 + other sheet as fillers - CMOS ISDI Image sensor. Sensor was allowed to heat up for an hour before measurements - 16 Photodiodes covering the sheets sequence 42, 55, 45, 38, 36, 43, 32, 48, 41, 8, 39, 40, 37, 35, 49, 9. - Optical fibre used with optical gel to couple LED to scintillator sheet n. 8
Aim: Compare light output from sensor and photodiodes. Plan is to insert light into sheet n. 8 and measure the light output with the CMOS sensor and different photodiodes arrays.
