Imaging Light Measuring Device Hardware Triggering

The patent replaces software-based triggering with hardware-based triggering. The control unit generates trigger signals that directly activate the image sensor and spectrometer through hardware interfaces, eliminating the variable command runtime of software execution. This hardware substitution ensures precise and consistent timing for both measurement devices, resolving the contradiction between operational control and timing precision.

The patent implements preliminary synchronization by generating trigger signals that simultaneously activate both the image sensor and spectrometer before the actual measurement begins. The control unit coordinates the timing of both devices in advance, ensuring they are ready to capture data at the exact same moment. This eliminates the need for extended measurement durations to account for runtime variability, thus maintaining reliability while minimizing dwell time.

The patent merges the triggering mechanism of the image sensor and spectrometer into a single synchronized operation. The control unit generates a unified trigger signal that simultaneously initiates measurements in both devices, combining their operation in time. This simultaneous activation ensures perfect data correlation between the two devices while maintaining simple control through a single trigger source, resolving the contradiction between control simplicity and data correlation.

The patent employs periodic or pulsed activation of LEDs synchronized with the measurement trigger. Instead of continuous activation, LEDs are turned on only for the brief moment when both the image sensor and spectrometer are capturing data. This pulsed operation allows sufficient light emission for accurate measurement while minimizing total activation time, thereby reducing heat generation and preventing spectral shifts caused by temperature rise.
