描述了一种激光热刺激器系统，其能够通过非接触式精确刺激器对皮肤热感觉和疼痛感觉进行心理物理学和神经生理学研究。二氧化碳激光器被用作热源，通过复杂的辐射计对皮肤温度进行闭环控制。已经实现了0.1°C至25°C的温度阶跃，上升速率大于30°C/秒。在0.3秒至20秒的脉冲持续时间内，温度可以保持在优于±0.1°C。
A laser thermal stimulator system is described which enables the psychophysical and neurophysiological study of cutaneous thermal and pain sensations by means of a non-contact, precise stimulator. A carbon dioxide laser is used as the heat source with closed loop control of skin temperature via a sophisticated radiometer. Temperature steps of 0.1°C to 25°C have been achieved with rise rates of greater than 30°C/second. The temperature can be maintained to better than ±0.1°C over pulse durations of 0.3 seconds to 20 seconds.
