Abstract Triangle orientation discrimination (TOD) is an observer task useful for characterizing the practical performance of electro-optical imaging systems. We generated simulated imagery of TOD targets viewed at various ranges through a High Definition Long-wave (HDLW) imaging system. The simulated imagery was presented to human subjects in a TOD experiment, and the probability of identification (PID) was determined as a function of range. We present the PID curves and show that TOD is suitable for field testing of ID range.
