Systems and methods for environmental control of vehicle sensing systems

An optical apparatus comprising:

• a cover having a vent hole to allow an airflow into the cover and a cover opening connected to a window;
• a housing having the window, the housing configured to accommodate a laser emitting device configured to emit laser pulses to an outside of the optical apparatus through the window;
• a fan disposed beneath the housing and configured to generate the airflow;
• a conditioning element having a plurality of fins defining a first portion configured to receive the airflow from the fan, the fins having a second portion curved relative to the first portion and configured to direct the airflow onto a window to provide conditioned air to the window;
• a frame covering the conditioning element;
• and
• a dual heat sink for removing heat generated by the apparatus,
• wherein the housing comprises a base and an inner housing formed on the base,
• wherein the base includes a base opening to allow the airflow,
• wherein the frame includes a shroud covering the plurality of fins, and
• wherein the dual heat sink has a plurality of radiating fins mounted on both one side and an opposite side of the inner housing.
