1. A photoelectric detection device with a sealed design and undistorted photoelectric signals, comprising: a vacuum sealed housing, a photodetector array, a photoelectric conversion and synchronous acquisition circuit, and a high speed transmission circuit board, wherein
the vacuum sealed housing comprises 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;
the photoelectric conversion and synchronous acquisition circuit and the 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; and
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.
