Abstract: A photoelectric detection device, including: a vacuum sealed housing, wherein the vacuum sealed housing includes a mounting interface for mounting the photodetector array so as to form a sealed space; the photodetector array has a detection surface facing an outside of the vacuum sealed housing and configured to receive multi-channel measurement optical signals; a photoelectric conversion and synchronous acquisition circuit and a high speed transmission circuit board are placed in the vacuum sealed housing, and the photodetector array is connected to the photoelectric conversion and synchronous acquisition circuit through a signal pin of the photodetector array; the photoelectric conversion and synchronous acquisition circuit is configured to synchronously convert the multi-channel measurement optical signals obtained by the photodetector array into multi-channel digital signals; and the high speed transmission circuit board is configured to perform a serial encoding processing on the converted multi-channel digital signals.
