Peak Signal:
Definition: Bit 8 = 1
Type:
• Value encoding (Bits 15, 14):
For geometrical quantities like thickness or distance
• 00: float in micrometers, including refractive index (geometrical thickness)
• 01: integer 16bit, scaled as fraction of measurement range, without refractive
index (optical thickness).
Distance and thickness values are given as: d[µm] = value * $SCA[µm] /
32768.
In order to get the geometrical thickness, the value has to be multiplied by the
index of refraction of the material.
• 10: 32bit integer value in nanometers, including refractive index (geometrical
thickness)
• 11: integer 32bit, scaled as fraction of measurement range, without refractive
index (optical thickness)
Distance and thickness values are given as: d[µm] = value * $SCA[µm] / (1 <<
31).
In order to get the geometrical thickness, the value has to be multiplied by the
index of refraction of the material. This format yields the highest theoretical
resolution.
For non-geometrical quantities (like intensity)
• Floating point values:
• 00: float
• 01: truncated 16bit integer value
• 10: 32bit integer value in 16.16 format
• 11: undefined
• Integer Values:
• 00: 32bit integer
• 01: least significant 16 bit
• 10: most significant 16 bit
• 11: undefined
