Pearleye P-007 LWIR
Pearleye P-030 LWIR The frame-sync output (active low) supplies approx. 900 mV at a termination
with 75
.
Conversion of image data to temperature data
Due to the internal LUT, the pixel information can be converted to a correspond-
ing temperature value.
For the Pearleye P-007 LWIR the following relation can be used:
T = r x DN + o
with:
DN: 12-bit digital value (pixel data)
T: Temperature value [°C]
r: Resolution (for Pearleye P-007 LWIR)
standard version: 0.03 °C
High Temp version: 0.05 °C
o: offset for DN=0 (for Pearleye P-007 LWIR)
standard version: -30°C
High Temp version: 0 °C
