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)
o: offset for DN=0 (for Pearleye P-007 LWIR standard version: -30°C)
The following diagram shows the result:
For the Pearleye P-030 LWIR the following relation can be used:
T = r x DN + o
with:
DN: 14-bit digital value (pixel data)
T: Temperature value [°C]
