The signal from the non-sensitive area is regarded as a kind of noise. And it is necessary to reduce the impact of the noise in design and application of LAPS array.
此处产生的信号将作为一种噪声被引入，减小这种噪声的影响是阵列化LAPS设计和应用中必须考虑的问题。
LAPS array usually USES LED array as stimulative light source. LED has a large divergence Angle, so it is difficult to avoid some light irradiating on the non-sensitive area between sensitive areas.
由于阵列化laps一般采用LED阵列作为激励光源，而LED的发散角较大，所以在实际应用中难以避免有部分光线会照射在各敏感区域之间的非敏感区域上。
Spatial non-uniformity is measured by applying a small laser spot scanning across the detector sensitive area.
面响应不均匀性的测量是利用小的激光光斑在探测器的灵敏面进行二维扫描。
