Shooting device, sighting apparatus, imaging rangefinder and adjusting method thereof

An imaging rangefinder adjustably mounted on a sighting telescope, comprising:

• a power supply,
• a control module electrically connected to the power supply,
• an imaging module electrically connected to the control module,
• a ranging imaging module electrically connected to the control module,
• a display module electrically connected to the control module, and
• an eyepiece system showing an image shown by the display module, wherein an image from the sighting telescope is transmitted to the control module via the imaging module, the image shown by the display module comprises the image from the sighting telescope, an image from the ranging imaging module, and ranging information and ranging aiming point from the ranging imaging module;
• and
• wherein the imaging module comprises a first reflecting system and a first imaging sensor, optical paths of the image from the sighting telescope are folded and reflected by the first reflecting system to the first imaging sensor, and the first imaging sensor converts an optical signal into an electrical signal and transmits the electrical signal to the control module.
