Sonic-vision is "supposedly" motion based. Unless the trap is moving then there should be zero possibility seeing it.
Perhaps ultra-vision?
I'm not so sure about all of that. Ultravision has to do with light just above visible light in frequency. Unless the trap is giving off ultraviolet light, ultravision won't work. It may be possible for a magically-triggered trap to give off this energy.
A trip wire trap would be visible to sonicvision when a breeze makes the wire vibrate.
A proximity trap might use ultrasonic waves and might be detectable with sonicvision. If it uses magic then ultravision might do it.
A pressure plate trap would be more difficult to detect but not impossible. Since the plate would be suspended apart from the surrounding ground material, temperature changes would occur at a different rate. For example, if a room suddenly were to get warmer or cooler, the pressure plate would reach the new temperature sooner than the surrounding material. Infravision would detect this.
But having said all of this, I'd rather not have traps. Those of us who solo would get mighty ticked off about traps if we aren't the trap-sniffing class. It's bad enough to have our health almost at zero when we manage to run away from a group of mobs. It's quite another to get killed by a trap that we couldn't possibly detect along our route.
