OPTICAL DEFLECTOMETER Russian patent published in 1997 - IPC

FIELD: measurement technology. SUBSTANCE: deflectometer has objective, prism unit forming two optical channels and sight targets located in each channel. All the above-indicated components are positioned in succession. Every sight target is made as radiator. Deflectometer is provided with two devices which control sight targets. These devices are coupled by series-connected coordinate receiver of optical radiation, receiver power supply unit, switch, analog-to-digital converter and programmed controller, controller keyboard, indicator, and temperature-sensitive transducer. Other input of switch is connected to output of temperature-sensitive transducer. Each radiator input is connected to output of respective radiator control device. Inputs of control devices are connected to corresponding output of programmed controller, and other input of programmed controller is connected to controller keyboard output. Other output of programmed controller is connected to indicator input. Provision is made for individual way of setting up the circuit elements. EFFECT: higher results of measurement. 5 cl, 3 dwg
