5 results about "Time of flight" patented technology

The invention discloses a solid-state multi-line ranging device, which comprises a emitted light module, a ranging module, an image sensor and a spectroscope, wherein the emitted light module emits infrared detection light, the infrared detection light emits into the environment and is reflected when encountering a measured object; the infrared detection light and environment visible light reflected by the measured object incident on the spectroscope, and the spectroscope separates the infrared detection light from the environment visible light; the ranging module receives the infrared detection light which passes through or is reflected by the spectroscope, and obtains a distance between the ranging device and the measured object based on a time of flight method, and/or the ranging device obtains intensity of the received infrared detection light; and the image sensor receives the environment visible light which is reflected by or passes through the spectroscope, and obtains image color information of the measured object. The solid-state multi-line ranging device does not have a mechanical rotating device, is more stable, and has longer service life.

A time-of-flight mass selector includes a first ion lens for converging ions, a flight tube into which ions which enter from the first ion lens are introduced, the flight tube having equipotential space therein, a second ion lens for converging ions having passed through the flight tube, and a chopper for a gate for pulsing the ions converged by the second ion lens.

The invention relates to a trace organic matter detection technology, and aims at providing an automatic trace organic matter detection gas circuit system for dioxin detection equipment. The system comprises gas inlet tubes of flue gas, standard gas and purge gas, and a pulse valve arranged at an inlet of a time-of-flight mass spectrometer, wherein the flue gas, the standard gas and the purge gasenter a preconcentrator through three-way joints; an outlet of the preconcentrator is sequentially connected with a gas chromatograph and the pulse valve; a gas outlet hole is formed in the middle ofa pulse valve flange; a gas inlet tube is communicated with the gas outlet hole to form a valve body channel; a standard gas tube and an exhaust tube that are communicated with the valve body channelare mounted on the side edge of the flange; the gas circuit system is mounted in a cabinet; and the gas inlet tube of the standard gas, the gas inlet tube of the purge gas and the two gas inlet tubesof the flue gas are mounted on a cabinet body of the cabinet via an integrated gas circuit board. According to the system, tubings are more reasonable and tidy in arrangement, strong in interchangeability and convenient to dismount, and are connected in a clamping and sleeving manner. The pulse valve can achieve a function of supplying standard gas for equipment standardization and equipment operation condition detection.
