A heat exchanger usable with a ventilator, the heat exchanger having an improved structure so that air passing through the heat exchanger may be prevented from leaking. The heat exchanger of the general inventive concept includes a heat-exchanging element having a plurality of liners stacked in a uniformly spaced state and a plurality of spacers disposed between the liners to define air passages, and corner guides respectively coupled to corners of the heat-exchanging element. Each of the corner guides includes a guide channel forming a space to receive the corner of the heat-exchanging element so that the corner guides securely come into close contact with the heat-exchanging element, and to minimize a loosening of the corner guide due to an adhesive applied between the heat-exchanging element and the corner guide.

Provided is a frequency shifting optical swept light source system. The system includes a light source that emits light; an amplifier that amplifies the light output from the light source; an optical converter that shifts a frequency of the amplified light and compresses a spectrum of the amplified light; and a controller that controls a current signal applied to the light source such that a repetition rate of the light output from the light source is adjusted, so that an intensity of the amplified light is adjusted, to thereby adjust a position of the compressed spectrum with respect to a predetermined frequency band.
