研制了一种基于数字数据处理的高速二维表面光电压（SPV）传感系统，并将其应用于化学图像的在线监测。该方法将扫描光斑产生的SPV信号直接存储在计算机中，并通过数值计算在分配的存储器中并行进行所有测量点的信号积分，从而在原理上可以将测量时间缩短到与光斑扫描时间一样短。对于6400个数据点的图像的形成，所提出的系统需要约30分钟，这是至少一个数量级的速度比传统的模拟SPV系统。
A high speed two-dimensional surface photovoltage (SPV) sensing system based on a digital data processing was developed and applied to an in-situ monitoring of chemical images. The SPV signal generated by a scanning light spot was directly memorized in a computer and signal integration of all measurement points was carried out in parallel in allocated memories by numerical calculation, which made it possible in principle to reduce the measurement time as short as the scanning time of the light spot. For the formation of the image of 6400 data points, the proposed system needs about 30 min which is at least one order of magnitude faster than that of a conventional analog SPV system.
