Herein, the spatial-energy profiles (SEPs) of the recorded signal were numerically studied at different shapes of the illumination pulse and ratios between the durations of illumination τ_p and registration τ_g pulses at a fixed delay distance. It was established that at τ_p < τ_g and τ_p = τ_g the characteristic visibility distance ranges do not depend on the shape of the illumination pulse. For their determination it is possible to use the previously obtained expressions for square wave illumination pulses. As a rule, for the cases considered at τ_p > τ_g SEP is a convex asymmetric curve with one maximum in a point S_max. For the simplest forms of illumination pulses designed by triangles or trapezoids the analytical expressions were obtained, allowing calculation of the value S_max from the known delay distance and illumination pulse duration. For the correlation τ_p > τ_g, the method of the calibration constant was also proposed to determine the distance S_max in the case of a real illumination pulse shape.

在这里，记录信号的空间能量分布（SEP）在不同形状的照明脉冲和固定延迟距离的照明 τ _p和配准 τ _g脉冲的持续时间之间的比率下进行了数值研究。已经确定，在 τ _p < τ _g和 τ _p = τ _{g 时}，特征可见距离范围不取决于照明脉冲的形状。对于它们的确定，可以使用先前获得的方波照明脉冲表达式。通常，对于在 τ _p > τ _g处考虑的情况，SEP 是一条凸不对称曲线，在点 S _max处有一个_最大值. 对于由三角形或梯形设计的最简单形式的照明脉冲，获得了解析表达式，允许根据已知的延迟距离和照明脉冲持续时间计算值 S _max。对于相关性τ _p > τ _g，还提出了校准常数的方法来确定真实照明脉冲形状的情况下的距离S _max。
