[Laser] Preferred Optical detector device

[Tim Toast]

Hi Paul
 
Here are some common photodiodes mentioned or used 
by people on this list:
 
PD-3
PD-4
PD-10d
020-72-60-541
CLD-142
PDV-V417-ND
PNZ331F
PDB-V107
PDB-V112
PDB-V117
SFH-214
SFH-203
BPX65
BPW33
BPW34
IPL10040DW
OSD1-5T
RT5-2354DTS-C2
RT5-2394
S2386-18K
S5973

These diodes have surface areas ranging from less than 
1 mm, up to about 1 sq inch or so. I think for NLOS you 
would want one with a large area generally for a large 
FOV. The idea being the receiver field of view should at least 
match the size of the tx spot on a cloud or other object.
