The invention provides a parallel optical scanning detection device, which comprises a light source unit, an interference unit, a light splitting unit, an optical path adjusting unit, a plurality of scanning units and a receiving unit. The light source unit provides an initial light source to the interference unit, and the interference unit divides the initial light source into a reference light source and a sample light source; the light splitting unit divides the sample light source into a plurality of sample light sources, the optical path adjusting unit adjusts the sample light sources into scanning light sources with different optical paths, and each scanning unit receives one scanning light source and scans a sample through each scanning light source, such that the scanning units receive the detection light sources reflected or scattered from different positions of the sample respectively. The receiving unit receives the reference light source and the detection light sources and performs light coherence effect on the reference light source and the detection light sources respectively, so that the receiving unit generates optical information of coherence effect of different optical path differences. The optical information is processed and analyzed by a computer to synchronously obtain optical coherence tomography scanning images at different positions of the sample.
