    • The microwave switch includes a housing (1) and a rotor (2) having a rotor axis (A). The rotor (2) includes respective plate-shaped parts (10,20) having corresponding ring-shaped outer surfaces (OS, OS′) and walls (15 to 18) extending between the plate-shaped parts. The rotor (2) is provided with through-going passages (7,8,9) extending transversely to the rotor axis (A) between the plate-shaped parts (10,20) and the walls (15 to 18). Grooves (6) for improving isolation of the passages (7,8,9) are provided only in the ring-shaped outer surfaces (OS, OS′) and extend longitudinally substantially parallel to the rotor axis (A). The grooves (6) open into the passages and the passages are bounded by the plate-shaped parts (10,20) in both directions of the rotor axis.

    • In a method for measuring the transmit time of light, in particular for cameras, a first light signal which is clocked by a first clock controller (16) is input into a light system (14) by a light transmitter (12) and is reflected back to a receiver photodiode (13) by means of a reflective objective (O). The photodiode (13) determines a reception signal as a result of the first light signal. By virtue of the fact that a further light signal which is clocked by a further clock controller (17) is input into the photodiode (13) at an angle with respect to the first light signal and is mixed at the photodiode (13) with the first light signal to form a common reception signal (S13), that the common reception signal (S13) is filtered with a filter (25) whose frequency response corresponds to the frequency of the clock difference in order to form a filter signal, in that the clock signal of the first clock controller (16) and of the further clock controller (17) are also mixed in a mixer (30) in order to form a mixed signal and in that the phase shift between the mixed signal of the clock controllers (16, 17) and the filter signal is used to determine the transit time of light, a method for measuring the transit time of light is provided which can operate in particular with cameras even with relatively inexpensive components and relatively low-frequency amplifiers.
    • 在用于测量光的发射时间的方法中,特别是对于照相机,由第一时钟控制器(16)计时的第一光信号由光发射器(12)输入到光系统(14)中并被反射 通过反射物镜(O)返回到接收器光电二极管(13)。 光电二极管(13)确定作为第一光信号的结果的接收信号。 由于由另一个时钟控制器(17)计时的另一个光信号相对于第一光信号以一定角度输入到光电二极管(13)中,并且在光电二极管(13)处与 第一光信号以形成公共接收信号(S13),公共接收信号(S13)用频率响应对应于时钟差的频率的滤波器(25)滤波,以形成滤波器信号,其中 第一时钟控制器(16)的时钟信号和另一个时钟控制器(17)的时钟信号也混合在混频器(30)中以形成混合信号,并且在时钟控制器(16)的混合信号之间的相移 (16,17),并且滤波器信号用于确定光的传播时间,提供了用于测量光的传播时间的方法,即使在相对便宜的组件和相对低频放大器的情况下,它也可以特别用于相机。
