A transmission unit of a wireless optical charging system considering user safety according to the present disclosure includes: a light source unit that generates laser light; an output unit that outputs the laser light to an outside; a reflected light output unit that is located between the light source unit and the output unit and outputs reflected light in which the output laser light is reflected from a reception unit and returned; and a light generation control unit that controls a generation of the laser light from the light source unit according to a result of determining whether a user is located between the transmission unit and the reception unit based on the reflected light.

Transmission unit of wireless optical charging system considering user safety

Provided is a multi-wavelength wireless optical charging system, which includes: a transmitter splitting low-power light of a predetermined threshold value or less into a predetermined range of wavelengths and transmitting the split light onto a space; and a receiver receiving the light transmitted from the transmitter and generating energy from multi-wavelength light which is light corresponding to a plurality of predetermined wavelengths in the received light to charge a device.

Multi-wavelength wireless optical charging system and method

An optical rotary junction module for an OCT system according to the present invention includes an OCT connection part having a screw thread formed on an outer peripheral surface thereof, the OCT connection part being connected to an OCT system configured to produce light, a connecting/fixing part having a screw thread formed on an inner peripheral surface thereof and screw-coupled to and engaging with the screw thread formed on the outer peripheral surface of the OCT connection part, a first housing having a screw thread formed on an inner peripheral surface of one end thereof and a screw thread formed on an inner peripheral surface of the other end thereof, the first housing having one end screw-coupled to the connecting/fixing part, a second housing screw-coupled to the screw thread formed on the inner peripheral surface of the other end of the first housing, a hollow motor inserted into the second housing and configured to generate rotational power, and an adapter configured to be coupled to an imaging catheter configured to be inserted into a blood vessel of a human body and transmit light received from the OCT system. The optical rotary junction module has the effects of reducing noise generated during high-speed rotation, and preventing failure caused by abrasion or the like. Moreover, the module may be structurally simplified and reduced in size, and the product cost per unit thereof may be lowered by minimizing the components.
