DEVICE FOR DETERMINING DIRECTION OF DIRECT BULLET SHOT Russian patent published in 2021 - IPC G01S17/88 

FIELD: laser locators.

SUBSTANCE: invention relates to laser locators and can be used in forensic ballistics to determine the direction of a direct bullet shot. The technical problem of the invention, which coincides with the positive result of its application, is to increase the accuracy and range of determining the direction of a direct bullet shot in all weather conditions. The device for determining the direction of a direct bullet shot consists of a guide provided with a conical insert and made, for example, in the form of a rigid spoke, on which a focusing system is fixed, connected by a light guide to a laser radiation source, while the optical axis of the focusing system is coaxial with the guide. A block of photodetectors is fixed on the guide, the outputs of which are connected through a multiplexer to the input of the control and measurement unit, and the output of the control and measurement unit is connected to the input of the switch and the control inputs of the optical switch and multiplexer. The switch outputs are connected to a block of pulsed laser radiation sources having different radiation wavelengths, the optical outputs of which are connected to the inputs of the optical switch. The device also contains a power supply unit for pulsed laser radiation sources connected to the switch and a GSM module connected to the control and measurement unit. The block of photodetectors consists of photodetectors with maximum sensitivity at wavelengths corresponding to sources of pulsed laser radiation.

EFFECT: accuracy of bullet shot is increased.
