3-1 Setting the Measurement Start Timing
Internal Processing of Sensor Controller
The Sensor Controller performs processing in the following 3 parts according to the logical beam sent from the
Sensor Head. Since each part is performed in parallel inside the Sensor Controller, the measurement cycle is
determined by the part with the longest processing time. When the measurement cycle is shortened, the
logical beam exposure time shortens, so the measurement accuracy of targets to measure with lower
reflectivity may not meet the specification. Also, due to the processing time of measurement processing and
output processing, the measurement cycle cannot be below 20 us.
The Sensor Controller starts exposing logical beam when the measurement start timing is specified.
When the light power is 100%, exposure starts when the measurement starts, but when the light power is less
th
an 100%, th
ere is a period with no exposure after the measurement starts. The exposure starts when the
measurement starts and ends when the measurement cycle ends.
