Provided are a wavelength conversion apparatus, a light source system including the same, and a display device including the light source system. The wavelength conversion apparatus includes an angle deflection region and a wavelength conversion region for converting incident second light into excited light and then emitting same. The angle deflection region includes deflection units, each of which includes a light emergent face for emitting first light. A first included angle is formed between the light emergent face and a reference plane. First included angles between light emergent faces of at least two deflection units and the reference plane are not equal. The deflection units are located on a light path of the first light in a time sequence, so as to change an emergent angle of the first light in the time sequence, such that the first light is successively scanned at a preset position to form virtual pixels.

A laser scanner determines the direction and distance of one or more targets by emitting two substantially parallel beams and receiving respective return beams. Components for handling the received beams are affixed to a monolithic block to ensure fixed relative placement. The direction of the target is determined using an optical encoder to reduce the timing window for interpolation to a fraction of the time it takes for the scanner to make a full revolution. A PLL trained by recent segment timing further improves accuracy and precision. A detection algorithm adapts detection thresholds for the different signatures of return signals depending on the distance to the target. Distance calculations are also adjusted for thermal expansion of the scanner components by including a temperature-variant thermometer output signal in the distance calculation algorithm.
