Getting the eval board the AFE4950 (mother board) with the SFH7072 sensors
- The sensor board supports 4LEDs, I am wondering can we replace this with a laser? Is there enough power for a 0.5W laser? If these are the electrical specifications of the laser:
- Threshold Current: 0.4 A
- Operating Current: 1.1 A
- Operating Voltage: 2.0 V
- TEC max Current: 2.5 A
- TEC max Voltage: 6.3 V
- Monitor Photodiode Range: 2000 μA
- Thermistor: 10 (±5%) kΩ (@25℃)
- Slope Efficiency: 0.7 W/A
And general specifications of the laser:
- CW Output Power: 500 mW
- Center Wavelength: 785 nm (±0.5 nm)
- Spectral Width: < 0.1 nm
- Temperature Tuning Coefficient: 0.01 nm/℃
- Current Tuning Coefficient: 0.05 nm/A
if 500mW is the max power we can use, can we just set that laser to 50mW because this is the amount of power we need.
- How do we control exposure time of the photodiodes?
- How do we control sampling time of the photodiodes?
- Can this be used for speckle contrast imaging?
- Can linux interface with the board?
- Storage available on the board? Any sort of support for microSD cards?
