▎ 摘　　要

NOVELTY - The detector has a substrate located at a lower portion of a detector main body. A supporting layer is located above the substrate. A piezoelectric film is located at a center portion of an upper portion of the supporting layer. An electrode is located on two sides of the piezoelectric film above the supporting layer. A photoacoustic film is located at a center portion of the piezoelectric film, where thickness of the supporting layer is about 200-1000nm, thickness of the piezoelectric film is about 500-5000nm and thickness of the photoacoustic film is about 100-2000nm. USE - Pulse light detector. ADVANTAGE - The detector has better photo-acoustic effect and piezoelectric effect, and can quickly and accurately measure broadband spectrum of pulse light. The detector is simple in structure, and has high detection sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a pulse light detector manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a pulse light detector.
