The project of the eye-safe High Spectral Resolution Lidar with a wavelength of 532 nm is proposed. Absolute calibration is provided by the molecular channel with iodine cell cavity for filtration of the aerosol signal. Transmitter has a laser beam expansion via receiving telescope to have a design with high thermo-mechanical stability to install small field-of-view and substantially reduce background sky noise. A detailed optical diagram of the transceiver is provided by the transmitter and receiver located on different sides of the optical bench. Characteristics of the laser and the system are given. Calculated lidar returns and errors of measurements are estimated. To have ten percent accuracy in troposphere, the aerosol backscattering and optical depth time of averaging should be from ten seconds to one minute. Proposed system must run continuously and be unattended.
