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
