Bernard do you have a solution for this or should we try common collector receivers?

Based on previous posts, I have assumed the following requirements & conditions:
- laser rotates at 600 RPM
- detector bar to work at a range of 100m from the laser source
- 30cm long detector strip
- 4 detector strips required for 360 degree coverage
- Detector device diameter is 5mm
- Laser beam spreads to 15mm at 100m distance
Evaluating design requirements:
- 600 rpm is 10 RPS, or 100mS per revolution
- Velocity of the beam at 100m is; pi X 2 X radius / 100mS = 6,280m/S
- This translates to 6.28mm/uS
- So the 5mm detector is fully exposed to the 15mm wide beam for only 10mm of travel, which is 10/6.28 or 1.59uS.
- The switching speed for the detector should be at least 10X as fast, or 150nS
- The beam intensity will be reduced a lot by a dusty environment
- Youll need to have a top notch, fast, sensitive detector for this application"
Bernard do you have a solution for this or should we try common collector receivers?
Best regards
