Preliminary

● Performance Measurements

The parameters in the Characteristics tables were

gathered using the transmitter jig in Fig. 2, along with

the receiver jig in Fig. 3.

1.

Linear Reception: Distance between transmitter

and receiver: 0.2 to 15.0 meters; detector face illu-

mination: Ev < 10 lx,

 = 0°

2.

Reception Angle Sensitivity: Distance between

transmitter and receiver: 0.2 to 12 meters; detector

face illumination: Ev < 10 lx,

  30°
