A new equipment for recording jaw movements in animals by use of a He-Ne laser and a phototransistor (PhT) array is described. The principle of operation of this equipment is that the beam angle of the He-Ne laser is continuously controlled to irradiate the center of the PhT array by a feedback mechanism composed of a microcomputer (CPU) and XY scanners. The driving currents sent from the CPU to the XY scanners are utilized for monitoring two-dimensional jaw movements. The linearity of this recording system is preserved both vertically and horizontally over a range of 11 mm from the center of the scanning field of the laser beam within less than 1.5%, which is satisfactory for monitoring rabbit jaw movements. When this equipment was applied to the rabbit, there was no sign of disturbance to the animal during chewing carrots.
描述了一种利用氦氖激光和光电晶体管（PhT）阵列记录动物颌骨运动的新设备。该设备的工作原理是，通过由微型计算机（CPU）和XY扫描仪组成的反馈机制，连续控制氦氖激光的光束角度，以照射PhT阵列的中心。从CPU发送到XY扫描仪的驱动电流用于监测二维颌骨运动。该记录系统在垂直和水平方向上，在距激光束扫描场中心11毫米的范围内，线性度保持在不到1.5%，这对于监测兔颌骨运动来说是令人满意的。当该设备应用于兔子时，在兔子咀嚼胡萝卜的过程中没有对其造成干扰的迹象。
