1. Measuring system for correlation photoacoustic imaging was set up. An XY-stage for imaging experiment was designed and contructed along with the computerized controlling system.2. Correlation photoacoustic imaging experiments were conducted for a model sample with three layers, and for natural sample of mica and painted materials. The resolution of the system was 10 in plane and 15 in depth. These values were later improved by use of commercially available XY-stage and control system.3. Detections by photothermal deflection and by photothermal radiation methods in place of photoacoustic detection were tried with successful results. By the former method, the limitation on sizes of sample investigated was removed, while by the latter mothod troubles arising from the resonance of sample cell were removed. Use of these two detection methods have been proved to be useful for the development of future works of depth-resolved analysis.4. Results achieved in this project have been presented at meetings or conferences and published in journals mostly in the field of analytical chemistry. At the same time, the results have been collected and printed in a report form specified and sent to investigators concerned.

1.建立了相关光声成像测量系统。设计并沿着搭建了XY型成像实验台，并设计了计算机控制系统.对三层模型样品、天然云母样品和涂料样品进行了相关光声成像实验。该系统的分辨率为10在平面和15在深度。这些值后来通过使用市售的XY级和控制系统得到了改善。用光热偏转法和光热辐射法代替光声检测法进行了试验，取得了成功的结果。前一种方法消除了对所研究样品尺寸的限制，后一种方法消除了样品池共振所带来的麻烦。这两种探测方法的使用已被证明是有益的发展，未来的工作的深度分辨分析.该项目取得的成果已在会议或会议上发表，并发表在主要是分析化学领域的期刊上。与此同时，已收集结果并将其打印在指定的报告表中，并发送给有关调查人员。
